Has anybody every had any of the following faults? cooling fans running constant, engine running very lumpy, stability & EDC warning lamps on, BUT, engine oil/water ok, no smells, no noises?.
Wife used the car yesterday morning to pop up the shop, a round trip of no more than 2 miles.
Came back, parked the car on the drive as norm, locked it & came in the house. About 4 hours later, we went back out to the car to go somewhere but found the radiator cooling fans running for approx 30-40 seconds, then stop for about the same amount of time, then start up again. We were stood next to the car, which was still locked & i had the keys in my hand. I opened the car, popped the bonnet to double check the coolant level, which was bang on the mark with no leaks. I went to start it but found the battery flat.
Jumped started it off the wifes polo, the fans stopped doing what they had been & all seemed well. went out, no probs, returned home, pulled on the drive & switched the engine off. Got out the car, locked it & just as we got to the front door, the fans kicked in again, i'm stood there, with the keys in my hand & the car locked. I then assumed the fans must run through a control unit & THAT must be the problem, so short term my plan was to remove the fuse for the fans & get it sorted monday.
Jumped in it last night to go to work, shot off down the motorway & then the problems started. cruising along at a nice 70ish when the stability warning lamp & the EDC warning lamps came on together (amber) along with total loss of power. I hadn't gone through any puddles (dry roads) & hadn't had any sort of traction or wheel spin problems. Got into the hard shoulder, turned the engine off & the fans are going again. Temp gauge is reading norm, popped the bonnet & again, the coolant level is bang on. Then noticed that it will hardly rev & trying to move it along the hard shoulder it was more "bunny hopping" than driving. There are no funny noises, even running as bad as it is it's as quiet as anything, theres no funny smells of any sort, no oil or coolant leaks, but it's now running really rough, like its only running on 3, & just dont want to play.
The car is the A4 1.8T 20v 190bhp s line, engine code BEK (i think, or is it BEX?), 74,500 miles with a full service history, inc cam belt, etc. It has had the Audi coil pack warrenty done & i even had the oil pump pick up pipe done on the last service & until yesterday the car has been a legend, absolutley faultless. I know its got to go in & have the faults read but just wandered if anybody has had or know of a similar problem. I am an ex truck mechanic so i like to think i'm still mechanically minded, but this has me stumped. The only suggestion someone has come up with thus far is the MAF sensor?
Just to mention, went out to it this morning, jumped in it & went around the block, no problems, revved up a treat & was as responsive as normal.
Sorry for the essay, just wanted to get all the info down in case this rings any bells with someone. Fingers crossed it isn't an ECU problem!
