116i 5 door petrol/manual 2009 - traction control light flashing on and off intermittently combined with momentary episodes of loss of power. Slightly touching the accelerator meant I could keep going, slowly, no acceleration. managed to find some power and acceleration in 3rd but as soon as changed up loss of power again. BMW dealer says 2 x drive shafts are corroded and the traction control sensors are detecting this and kicking in intermittently causing the loss of power. Their cost for replacing drive shafts and sensors £1500. Any thoughts? Am I being ripped off? Can it be done cheaper? What would you do in my situation?

A friend of mine had the same problem on his 120d.. he paid around £700 for all the parts but fitted them himself. Perhaps get a decent indy to give you a quote?

i had the same problem
Hi there,
I had this exact same problem a few years ago. The car would lose power and the traction control light would flash. A temporary fix is to disable the DTC. If you press the button down for a few seconds then the traction control light is on permanently but you don't have the loss of power (juddering in my case). The DTC button in my car is on the middle of the dashboard. I could drive my car perfectly when I disabled the DTC but it didn't obviously fix the problem.
I took my car to a bmw specialist and when I explained the problem he said its the sensors. What he did is put a bracket round the sensor? Sorry I don't know more than that but it was a £300 fix and the problem has never returned.
I drive a 118d 2005
Hope this helps.

DTC Light on loss of power
Hi i had the same problem with my 2006 318i, I was quoted £600.00 by a BMW specialist for two new rear ABS sensors and two new reluctor rings, also quoted £1600.00 by BMW main dealer for two drive shafts, I spent a few weeks looking around and I tried Euro car parts they quoted £230.00 for the parts, still thought I could do better, so went with UK parts direct, they do money off if you buy them as a set, I got two reluctor rings and two ABS sensors for £62.50 including next day delivery, (and they come with a lifetime guarantee) my local garage charged me £108.00 labour (two hours work) total cost £170.00, and the car drove like brand new, in the mean time hold the DTC button down to turn ABS off, otherwise your car will keep going into limp mode.

Sounds like the reluctor rings have corroded on the drive shafts very common issue. If you don't know, these are basically a toothed wheel that the ABS sensor is pointed at to determine the car's wheel speed. When they corrode they swell up and begin touching the abs sensor itself making your traction control system twitch. Press your DSC/DTC button once to disable it whilst you get this issue sorted.
The reluctor ring can be replaced, you don't need a whole drive shaft, BMW say you do as they don't sell the reluctor ring separately. Don't pay their prices.!! To replace them you need to pop the hub nut off, pull the spline through the hub and then you can get the old ring off once the end of the shaft is free from the car. Clean up the area the old ring was on then pop new ring on. Or a mechanic can do it easily enough.
Here is what you need.
Rings:
BMW 1 SERIES ABS RELUCTOR RING E81 E82 E87 E88 (03-14) REAR - PRO-COAT - ABS301 | eBay
You may need some rear ABS sensors too if they have been grinding against the ring the tips will be worn through.
