BMW Repair Questions? Ask a Mechanic for Answers ASAP
what faults are stored in the car's computer?
what warning lights are on the dash?
what exactly did the transmission shop do to try and fix it?
I had another german car expert in Keynsham look at the car and he seemed to indicate a problem with the electronic chip but that the only solution is a new gearbox at about £1500. No warning lights are on. As to the exact details of what the transmission specialist did, I just don't know. They simply said they were rebuilding the box or rather building a new box from scratch. I am a total amateur at mechanics and have no idea what they actually did.
I'm sorry, I just don't know. They simply referred to the 'electronic chip controlling the gear changes' and that this was a well known fault with BMW 5 series models 1996 to 1998.
I have found the Bristol Transmissions invoice and they charged for :-
1. Remove and install transmission - 3 hours.
2. Recondition ZF5HP18 auto transmission and torque converter.
3.Supply and fit oil cooler assembly, transmission ecu, gear lever assembly and throttle body.
Hope this helps but if not then I guess we had better call it a day.
A quick follow up - perhaps the guys who said 'chip' meant 'ecu' and were simplifying it for me - just a thought.
