E46 B3 Saloon 2002 Torque Converter and Steering Wheel Judder
Re: E46 B3 Saloon 2002 Torque Converter and Steering Wheel Judder
As mentioned privately to you yesterday but added here for general debate, I can't help wondering whether all the front end engine issues - misfires etc - are linked to bad signals coming from the lambda sensors.
A problem with the lambdas will force the EMU to adjust fuelling etc to correct the exhaust gas output which, if the lambda signal is wrong in the first place, will push the adjustments at the front end further the wrong way - if you catch my drift. Basically it is a feedback loop which, if driven by erroneous signals at the lambdas will throw the rest of the system out.

Re: E46 B3 Saloon 2002 Torque Converter and Steering Wheel Judder
ive never across several e39 and e46 cars and many miles between them had a lambda sensor fail
i have however had rough running issues arising from cam sensors, split air intake boots, duff spark plugs, ccv, head gaskets and so on

For what it's worth, my B3s starts rough and then smooths out very quickly. I do get the occasional lean code which may be a sensor on the way out but am more thinking that it's a vacuum/air issue which is more likely on an older car. I did find that the exhaust vacuum pipes were not re-connected after one gearbox visit. There's one for the tailpipe valve at the back of the rear silencer and the other is on the LHS by the crossmember (leads to the vacuum tank). Worth a check.
It's probably worth getting B&M (in Yoker...? - if so, they did my pre-buy inspection in 2016) to do a smoke test which should identify if there are any issues with air/vacuum leaks before you fire the parts cannon again.
My gearbox is smooth after rebuild, now that I've done a fair few miles with a very slight change in note at low speeds in 4th/5th when the converter locks (roughly 40 mph and 1400 rpm).
Any help?

Great advice - I did have a lean code which was a sensor (but I did suspect a vacuum leak)DogWagen wrote: ↑Tue Sep 21, 2021 1:57 pmFor what it's worth, my B3s starts rough and then smooths out very quickly.

Re: E46 B3 Saloon 2002 Torque Converter and Steering Wheel Judder
I have and it caused all sorts of issues upstream - hence my suggestion. Replacing them is very easy (with a lift ramp) and not too costly. Of course, it depends on what the codes are telling you

Small update here and apologies I’ve been away and inactive for a while was away for 2 weeks and back in Scotland now.
I’ve dropped the car to B&M Centre in Glasgow to sort out the misfiring and engine choking issues. I took the car back to the gearbox place and the engine is misbehaving so bad it will be hard to do any real road tests and such so they suggested I get that addressed first and I can bring it back whenever without the need for an appointment due to the circumstance.
Fingers crossed it’s on the road to perfection now , it shall be going straight from one garage to another and most likely do a couple hundred mile run in it then tuck her away for the winter.
(If it’s something as simple as the fuel filter I’ll be laughing ! I really hope it is at this stage haha)

Oh wow that’s crazy; what a small world ! And that is exactly what I told them maybe even verbatim haha. Must have been the other lovely chap in the shop when I was there.
Please don’t judge my ALPIN badge , she will become an Alpina again. Last car wash made it go missing and a new one has been ordered and on the way !

I had my E46 B3 box rebuilt by mackies 9 years ago costing £2100 then and has been great ever since.
A very similar box in my Range Rover was rebuilt by them about 4 years ago and cost me £2700 and has been perfect
My warranty was 3 year 10k miles Maybe your 100k mile warranty was a typo?

Car was out of commission for the winter and only had the car back on the road the last few weeks , I was going though some personal issues recently that’s why I’ve not been active in these forums.
The gearbox seems okay now that it’s settled a little , a bit rough from 2nd to 3rd gear on a cold start but once the engine is warm it’s smooth as you like. The rpm doesn’t jump around anymore when cruising at high speed either so seems like the TC is okay , will monitor this over the next few weeks. I’ve checked the paperwork and it’s 3 years or 100k warranty whichever comes first.
I’ve also had my front shock absorbers replaced in the meantime. I decided to go OEM Alpina , I didn’t think anything else would suffice. They were £865 including VAT from FMW-Tuning. Paid £720 first then got a letter from FedEx saying I owe 20% VAT. What a lovely surprise.
I’m still experiencing a rough start up when cold , for about 20 seconds the engine jumps up and down in rpm until it settles and is fine. It is almost as if it is trying to find the right mix of petrol and air. I’ve had a 2 more hoses replaced as they were cracked and leaking , this actually made the running worse for a while until it sort of settled again. Other than that car is running beautifully.

Sounds like the air pump possibly on cold start, mine does similar
Re: E46 B3 Saloon 2002 Torque Converter and Steering Wheel Judder
Would that be the secondary air pump ?

Re: E46 B3 Saloon 2002 Torque Converter and Steering Wheel Judder
theres only 1 air pump i think. Its only activates from cold and pumps air into the Cats until they are warm
Re: E46 B3 Saloon 2002 Torque Converter and Steering Wheel Judder
Pretty normal behaviour for E46 B3 cold start up? Just let it do its thing for 20-30 seconds. Warms up quickly
