The Ecu on a friends early 1990 UK 940 turbo has failed. I haven't taken the lid off to look but there isn't a signal for the fuel pump relay but the car runs if I close the relay contacts manually. I have fitted my spare ECU off a lot later car and the car runs fine with this but would really...

Myself and possibly the supplier of water pumps to Volvo for petrol 200, 700 and 900 series cars are interested in any problems anyone has had with their water pumps. The part number of the pump in question is 271975 and it's the currently available version with the pressed steel impeller. I...

It's been a while since I last posted on here, my 940 has been behaving itself although it hasn't done a lot of miles. I came back on to have a look and see what the current situation was with water pumps now. Last time I asked about this I had been having problems with a genuine Volvo water...

I have finally got round to sorthing the brakes out on my 94 940. The standard brakes were OK but there have been a few times when things got a bit exciting. I actually fitted the big 302mm discs first but if you can get the parts fitting the later brake servo, pedal and pedal box first makes a...

I'm gathering a few bits together to fit 302mm discs to my 940 and have found a few things out about the caliper carriers. After reading a lot of threads I found that there are 2 part numbers for these from Volvo. The number listed on Vadis for early V70's is 8602456 There is also another...

I'm considering fitting a pair of 302mm discs to my late 940. I will need to buy the caliper mounts but was wondering which calipers to go for. Looking at Volvo parts info it seems there are 2 calipers I could use, one with a 57mm piston and the other has a larger 59.92mm piston. The larger...

Does anyone know if this 1306867 is the right number for the clamping flange fitted to a 940 Turbo Cat ? It also fits on each end of the downpipe on cars with TDO4 turbos. According to Vadis it's fitted to an 83 760 and most diesels including late 940's. I have also found a number for a repair...

I'm looking to get a stainless exhaust made for my 940 in the UK. I was thinking about the silencer (muffler) positions. Non cat cars had silencers under the floor at the front, the box would need offsetting on the pipe to keep some ground clearance though. Most systems I've seen just run with...

Ive got a small amount of vertical movement on my shock top nut. Is it the bearing itself thats worn or one of the metal sleeves ? The nuts are tight so I'm pretty sure it isn't them. I'm going to change the front struts but was wondering if I could fix the strut top rather than buy new ones...

I've been looking into what is available to fit on my 940 estate. I have nivomats on the rear so will probably fit Bilstein B6 shocks and heavy duty (overload) rear springs. I would really like to lower the rear slightly but not loose any load carrying capacity if possible. I can get Kilen...

I've raised the boost on my 94 940 and was wondering how much the standard PCV system will take before it stops working properly. My main concern at the moment is the pipe from the inlet manifold to the Y piece on the top of the oil trap. Been reading a lot and some articles suggest that too...

Lambda Sensor I have replaced or checked almost everything sensor wise on my car except for the Lambda sensor. I am thinking that it might be the cause of the strange idle speed I get after a cold start. The car seems to take a while to sort itself out and if I drive away too soon the idle is...

I fitted a new genuine Volvo water pump to my 940 about 7 months ago and it's started leaking quite badly from the drain hole. I wasn't all that impressed with this so called genuine part as it had a pressed steel impellor instead of the factory fitted cast one. In the UK this is normally a...

Before I get flamed (again !) I have read through many of the old posts. My understanding of boost spike was the initial level of maximum boost you get before it drops off slightly once the wastegate opens properly. Apart from this there aren't any other circumstances where spike will appear...

I've got a better airbox to fit to my car as the one I had had a broken clip on it. Anyway looking at the intake I was wondering if there would be any gain in opening up the unused hot air inlet and putting a hose in it to get some more air in the box. The air is normally drawn in from under the...

I don't want to start a fight but I'm trying to decide. I have been looking round in the UK at various chips that are available and had almost decided to buy some chips off of frpe82 but now that thelostartof has started to do them I don't know again. For what I am doing I don't need a higher...

I have decided to make myself one as I haven't got anything much on at work. Seems a bit of a pointless exercise really in some ways as you can get them off ebay so cheap but it gives me something to think about. I have ordered a couple of brass "T" pieces and some 3/16" hose tails from a...

Hello I have posted on here about the effects of removing the EGR system from my car but don't think (hope) that is the problem. I thought it would be a good idea starting again. To recap, I have a non turbo 940 auto and recently fitted a turbo engine and manual gearbox , wiring loom, engine...

When I fitted the turbo engine into my car I decided to remove the EGR stuff. I did this partly to simplify things (less to go wrong) and to stop the build up of any exhaust soot etc in the inlet manifold. I have been having problems with intermittent high idle speed since and have started to...

Hello I'm stumped my 1995 940 turbo is misbehaving and I really don't know what's causing it. I have just finished swapping the engine and gearbox plus any associated bits to make my car a manual turbo (it was non turbo auto before). From cold (overnight) the car apears to run ok. I do about 30...
