Hi!

I bought a bmw m sport last week and was very happy with it. It is 2008 and has 113k miles on. I paid 6100 from a private seller.

I've never owned a BMW, or an auto before so these may be normal problems I'm having. I have noticed some issues and would appreciate if somebody could give me a clue on what to expect once the indy garage looks at it on Thursday.

I've put 200 miles on it and noticed...

The coolant temp does not exceed 70 degrees no matter what (verified with the hidden features on dash). Probably my thermostat.

The steering wheel wobbles like crazy when braking from 80mph (didn't do this on the test drive). Also the brakes squeak at low speeds when braking and when steering right (brakes not applied) - this is really concerning me.

There is steering wheel wobble in general at around 70mph and there is a buzzing noise coming from the from the front end somewhere. (again wasn't on the test drive).

When idle in neutral, slightly tapping the accelerator makes the car rock (engine mounts I assume).

The gearbox is a mystery to me. If I am traveling at 30mpg and floor it (engaging the kick down switch) the car will shift into 2nd gear and the revs will increase to 2500rpm whilst the car is accelerating (as if a clutch is slipping)... It does this in other gears too.

Also at motorway speeds in 6th gear if i slowly push the throttle nothing happens until my foot is over half way down - then the revs jump up and it begins to accelerate. This also happens in other gears. It has recently had the transmission fluid changed (apparently).

Thanks for reading

Richard

doenst sound good,,first off your stats are gone,2nd your control arms and or drop links and other suspension compinents sound worn,,3rd,,your gearbox sounds knackered,,they have 5 clutches,,and yours sounds like clutch pack wear,,,usually clutch e i think,,worst case total rebuild or new box..i doubt weather a serrvice is gonna save it ie zf kit and oil,,other thing is,,get gearbox checked for leaks,,could have low oil,,and these boxes do not loike low oil,,its quite a procedure to put more oil in a s you have to go through zf guidelines etc..sounds like seller has had your ass...id not be happy..try and dig some info up on him,,might have joined forums for answers,facebook etc also..as soon as i bought my 335d with 95 k milesi had the gearbox serviced,,nowt wroing with it,,but they are due a service from 70 k miles,,and thats the gearbox makers guidelines not bmw

These are very common issues on big BMW diesels.

Temperature, you need to change coolant and egr thermostat. I would do this a priority as the low temp will stop your DPF regen from happening.

Brakes and steering wheel wobble/squeek, sounds like you have a binding front brake caliper. I'd swap change them and the front flexi hoses too.

Gearbox behaviour, sounds normal to me. The 6th gear push halfway down thing is normal, the torque converter will have 'locked up' at 6th gear speeds.

I would advise you to find a good independent bmw specialist to look at the car

Ask him to also check if the dpf is still there and has not been gutted

Make sure he also check the small turbo is still working

Thanks for the replies, guys. I have found a bmw specialist - remarkably it's the same who the previous owner has used so maybe they can offer some insight into the car.

Regarding 6th gear, it just doesn't feel right that I'm pushing the accelerator and nothing is happening. Is this actually normal? The fuel consumption gauge increases as I'm pushing down and nothing is happening too.

And what about 2nd gear seemingly slipping on the kick down? This is normal too?

Cheers for the advice about the thermostat and dpf - I didn't know this.

I'm still unsure what to do about the car, I am considering legal action. Could be painful as it was a private seller.

Sounds like a real mess and my sympathy.

I am not taking the side of the seller but this car was £40k+ when new and you paid just over £6k after 11 years and 113k miles.
Surely you expected the car to needs some major repairs now.

Cant say much about the autobox as i stay away from them. But sticky caliper and front control arms would be expected on a car this age.
I am guessing you not handy with tools otherwise checking the brakes and control arms easy DIY job.

If you planning to maintain a tired old beast 335d with garage you may need to start skipping meals and put money into a car fund .
You still not have to look forward to the turbo, not sure if that has single or twin.
I know this may sound like a put off but many E90 owners have tried to maintain cars with garage and bills can be eye-watering...specially when they see you drive in with a top of the range model and you have no clue about the mechanics of the car.


Not sure what legal action you take against a private seller as its normally sold as seen. That's why some people prefer to pay extra and buy from garage(not me ofcourse)

If i was in your shoes sell it now even if some loss before you start spending big money

I understand that, but the seller describes the car literally as no faults and drives superb. I did take repairs into consideration when I bought it but the autobox is my main concern.

I'll post my findings once I've seen the specialist and hope it can help others in the future.

You said during the test drive it was faultless and was happy to hand over the cash... see my point.
Its a risk we take buying used cars.

The 335d is a beast and chances are its been remapped and pushed hard most of its life, its not car thats driven slow as there are 320d for that.

With these high powered BMW, owners normally maintain them DIY or they have deep wallet for garage bills.

All the best mate

Cheers pal! I used to maintain my old mk4 gti turbo. I'm a bit intimidated when I look under the bonnet on this beast though! I'll have a good look around for some DIY tutorials for this, I really don't want to give up on it.

Assuming it has a standard torque converter then they can appear odd if you are not used to them. They are essentially a fluid link between engine and gearbox, like a propeller on a boat in water. They can feel like there is a wooliness to them, so it might be normal or could be bad. Check the fluid condition and level, there is normally a dipstick for the autobox.

Considering these diesels can last 300k+ miles with good maintenance (oil changes, transmission servicing etc) it's a joke you have these issues with the description of a faultless car. It's on what 113k, it's nothing! But the other chaps are right it does sound like quite a lot of your issues could be the transmission

so first and foremost I would say get yourself something to diagnose the car there's many routes and it will save you good money with little investment. The quick and convenient route is Carly adapter with the carly app, adapter costs around £30ish I think and the app can be upwards of £50 as they have some dreadful In app purchases which is a pee take considering it used to be a one off cost.. but yeah that's a popular option and to be fair you can get the carly app fully unlocked for nothing if you search around.

Second is a laptop with a K+Dcan cable using software such as INPA and ISTA+, can't get better than this but lengthy downloads and massive file sizes but the worlds your oyster and the software can be downloaded for nothing.

Going back to your issues, even if the transmission was serviced its important to note who serviced it, it's not hard but it has a very specific procedure such as topping up the oil, starting engine, running through gears, monitoring transmission oil temp, waiting till it gets to 50ish degrees (can't remember exactly) and then a final stop off while at that temp. So, assuming it was serviced as they said, did they do it right?.. also, did they use genuine ZF fluid, others mimick the genuine oil but as they're not 100% it can cause unexpected results.

Squeak while turning, depending what that actually sounds like it could be the brake dust cover behind the brake disc, usually gets bent while working on the suspension components. Brake squeak could just be copper grease.

Hopefully you have some luck with the car diagnosed but I would definitely get something to diagnose the car myself

Yea it has full bmw service history too, mostly main dealer. 113k was one of the lowest mileage examples I could find. The gear oil was changed at a specialist bmw garage less than a thousand miles ago.

I've discovered I have a bad wheel bearing aswell - only evident after a 45 mile journey (rumbling and extremely hot compared to the 3 other corners). I've bought another and plan to install over the weekend. This could potentially cause the brake issues I imagine.

Can you provide a link to the Carly adapter? I can see Bluetooth and wired versions etc.

I have it booked in for 9am at a specialist on Monday. I will be contacting the seller after I have had a diagnosis & I'll let you know what they say.

I got mine from Amazon as can be seen here:

riginal Carly Bluetooth GEN 2 OBD Adapter for Android - BMW, Mercedes, Porsche, Renault, Toyota - Lifetime warranty https://www.amazon.co.uk/dp/B0187HPAOS/ref=cm_sw_r_cp_apa_i_Q46cDbS3F00W6

The Carly for BMW app from the Play Store can be found here also.

https://play.google.com/store/apps/details?id=com.iViNi.bmwhatLite

There's also an interesting app that you may wish to look into called protool by bimmergeeks which can be found here

https://play.google.com/store/apps/details?id=net.bimmergeeks

And here's their website for more details

https://www.bimmergeeksprotool.com/

I can't comment on Protool yet as I need a USB C to USB A adapter for my phone as I already have a K+Dcan cable and unfortunately it doesn't work with the Carly adapter.

You'll have to post the dealership diagnosis as it's very strange.. the history, the test drive the bmw specialist transmission service would all indicate a well looked after car, but then you get all these issues.

Thanks for taking the time to reply - exactly what I need! I'm going to buy that module anyway. I already have a VAGCOM so I'm kind of familiar with tools like this.

I'll be in touch soon. Hopefully things are not as bad as I think.

If you are anywhere near me Ilford area i have the full BMW Carly.. Happy to let you use it for a KFC bucket for 1 :silly

I have the older licence Carly and it was a one-off and no further in-app purchase. Anyone purchase now is about £60 per year...yes per year

Fingers work just as well, touch one disc then the other, if you have the same amount of yelping then they are probably ok.
My mate drove his E90 with the rear caliper seized..The heat coming from the wheel was a give away. Also when the car was raised could not turn the wheel by hand.

You can buy repair kit with new pistons and boot about £30 and rebuild the pair

Yeah the passenger side is almost certainly binding. It's much hotter than the drivers side.

Also when parking up I could even feel the brake sticking when trying to maneuver.

Is there a simple solution to this issue?

I've uploaded some images of the brakes as they don't look standard. They're strange because the calipers are massive but the pads are really small.
