Firstly hello, great forum. I have been a reader for a while and the search button has been a real help so far!! ButÖ
I have recently purchased a 1999 146 2.0ti and have had a few issues since I bought it, most of which I have managed to get fixed thanks to reading posts on here.
I will give you a bit of background info (try not to fall asleep) so you may understand a little better and of course if someone else has the same problem will be able to help them too
When I got the car it seemed to run OK apart from the diesel sounding rattle from the engine (when hot, cold, whenever).
A short time later the suspension started making a lot of banging squeaking and other unsavoury noises, the car started running a little lumpy and the car started revving from 2000 rpm to 3000 rpm (this would happen on random occasions).
A visit to my local (recommended) specialist
(not main dealer) and he suggested that we replace a number of suspension parts. Unfortunately I do not know the correct name of all the bits but Ill try and describe them!:
Front shocks (ebach or something like that).
Wishbones (I think, heavy t shaped metal with rubber boot top and bottom with metal clamps).
Turret mounting? (metal plate with rubber in the middle, fits on the inside of the turrets at the top with 3 bolts).
Alignment of front wheels.
The result of the above work stopped the squeaking when moving the steering wheel and the majority of the bangs but when pulling away in first gear there is a distinct clonk. This can also be heard sometimes when you go over a speed hump but not always. Any Ideas? To make things easy we can call this question 1 !!
Also now (upon collection following the suspension work) the steering wheel started vibrating. Starting at low speeds 25 mph and gets worse the faster you go. The mechanic blamed this on deformed tyres and a lack of balancing, maybe so but it didnít do it before!! He told me that with the new suspension parts the car is more sensitive to the tyres. A couple of weeks later I took the car to a garage to check the tyres and they tell me that the tyres are deformed and shows me the drivers side inner tyre was now worn and broken down to the wire and rather dangerous. He tells me that this is the alignment that has caused this problem and needs 4 new tyres and realignment now!!
Question 2 !! does this sound correct to you?
On the side of the car running lumpy the mechanic suggested a general service including: Sparks, oil + filter change, air filter and to clean the sensors and injectors. He also recommended to replace the regulator in the alternator as it was broken, apparently this was the cause of the car revving randomly. Knowing more than my fare share of vehicle charging systems I was not convinced but it needed to be repaired anyway.
Now I did not do the repairs straight away due to lack of funds and a couple of weeks later, whilst driving the car would start to lurch down the road like doing bunny hops!! but in all gears (obviously it was not so bad in fifth gear) but in first and second it was enough to give you whiplash. This was happening randomly but more and more.
I booked the car in for the original service and to see what the new problem was. the day before my appointment with the mechanic the clutch broke!!
At this point I went all out and had the following work done:
Regulator for the alternator
Variator? (heavy metal tube like object with threaded screw on one end)
Timing belts (normal and double toothed)
Tensors x 3
Sparks x 8
Oil and filter
Clutch (all 3 parts)
The result of the work was: No more diesel sound, working clutch, no more bunny hops and the alternator good and stable. BUT the mechanic tells me that the car is still revving randomly and because of this he has reduced the cars idle so not to damage anything. He then suggested that the rev problem was infact the Butterfly Control? Something with a motor that regulates the air intake etc?
Now for 1 month the revs stayed good and I had no problems but the idle turned down to 600 rpm was a bugger!! The car would stall when slowing down and depressing the clutch so I re-regulated the idle back to 1000 rpm. Again all was good for about 3 weeks then out of the blue the random revving problem returned.
When this happens now I turn off the car and restart it until the problem goes away (sometimes first time others 5 or 6 times).
The car also is a little bet jerky in first gear (pulling away, accelerating in first then reducing acceleration) and a little when changing into second. Nothing like before when it did bunny hops but still, the money Iíve thrown at this car, it should go like a Rolls Royce
Question 3!! What do you think this rev problem is and HTF do I fix it?
Since doing this engine work the MPG has literally halved!! I think it used to do around 800Kms to the tank where now its more like 400Kms. To me the exhaust fumes also smell a little stronger or sweeter.
Any help you can give me on this matter would be gratefully received as I am at a bit of an end with this one.
Thanks a million.
