Just had the car down to Muj at Sams autos in Huddersfield after getting his number from an old post on the forum.
I expected some new, all singing all dancing modern tech shop. How wrong i was. Its a tiny little backstreet place with tools and parts all over the place, bit of a mess! but......... he knows his stuff on BMW's and other performance cars. He did a full diagnostic check, turbo pressures, check errors and reset etc and the best bit was he only wanted 20 quid! Aparently according to another bloke waiting he looks after ferraris and porsches for the local dealerships.
Anyway he advised me to take the car down in a months time at 65k for a new oil breather and turbo hose as pressure was slightly low, said he'd work with me to fit them so i can learn the ropes which is what i'm after. Perfect.
Asked his advice on tips to keep car running well. All he said was V-power fuel and oil changes every 7k ish on big diesels and a good run once a week, also recommended to do a dpf delete and bypass if short journeys are regular.
If your in Huddersfield area he's you man.
