Hello All,
New to the fourm, apologies if this has been done to death on other posts. I am looking for recommendations for parts please.
I have a 2.0 a4 avant tsfi b7 SE Quattro 2007 with 122k on the clock.
Long story short I have been chasing a vibration / misfire for several weeks I am now at a point where I don’t want to get rid of the car because of the parts and maintenance I’ve recently had done. I’ve spent just over 1700 on a timing belt, clutch, flywheel, coil packs, plugs, service, brakes, suspension arms, rear springs, cv joints... the list goes on. Some of this work was done by myself but I left the timing belt to the professionals.
To my frustration none of the above solved my vibration / misfire issue, I recently tried another mechanic, by this time the vibration that was previously showing at 3.5k revs + was now occurring all the way through the Rev range and a rattle could be heard on tick over making it easier to diagnose.
He has just stripped the car today and has found a broken balance shaft, badly worn oil pump drive and broken teeth on the sprocket where the oil pump chain runs.
From what I have read this looks to be a common problem upto 2008 b7s. Previous posts on this topic were rather old and generally only new engines were mentioned with people mostly suggesting that it was game over.
The engine was still running well and the car has been driving well even with this with vibration for several months. Was still driving well just before he stripped it. No oil pressure warning lights at all and the mechanic said the oil pump shaft was wedged so it was still pumping (luckily).
Does anyone know what the best route forward would be and what I have in store price wise ?
I am looking for parts recommendations, does anywhere sell full kits or carry out refurbishments?
Thank you in advance.
Cheers
