Plastik Parts Bumper and Door

Plastik Parts Bumper and Door

Any recommendations to get all the different colors of the plastic parts into one grey color? Unfortunately I had to change some of them. Now they all have different gray tones due to weathering.

Fuel Line

The part from the fuel rail snapped off in the fuel line and replacement is impossible to find.. does anybody have any extra for a 96 850r or any suggestions on what to do.

How fucked am I part 3

I’ve been gone for work for a couple of weeks so I wasn’t able to respond to everyone who gave me advice but thank you.

Anyways I finally got my parts today and now it’s running a lot better, still a lil rough I think but now’s it dies after like 20 seconds

I can’t think of anything cause everything was fine before except The battery’s completely dead if that plays a part or not idk

Speedo not working great

So my speedometer sometimes just stops working mid drive, could this be the gears behind it or could it also be related to the abs module because thats shat the bed as well

Motronicsuite Read Is Giving Me 64KB of Zeros Bad KKL Cable?

So I’m trying to read my Motronic 4.3 ECU with MotronicSuite.

I’m able to connect to the ECU, and MotronicSuite appears to communicate with it normally. However, when I use Read Flash Content, it downloads a 64 KB BIN file but the contents are usually all 00, so no actual ECU data is being read.

At one point, using another PC, I managed to save three BIN files, but all three had inconsistent results:

  • volvo.bin: 64 KB. All 65,536 bytes are 00. Empty / failed read.
  • volvo2.bin: 64 KB. Contains data only at the beginning; from approximately 0x0D75 onward, everything is 00. Very incomplete read.
  • volvo3.bin: 64 KB. Contains a lot of real data, but the last ~8 KB are 00. Partially successful read.

Does anyone have any ideas what could be causing this?

As far as I can tell, I’m following all the required steps and have the correct drivers installed. I’ve also experimented with the COM port settings in Windows, including the FTDI latency timer, but the results are still inconsistent.

At this point I’m starting to suspect a hardware issue with the KKL cable itself.

Extra info:

  • Volvo 850 T5, 1996
  • Bosch Motronic 4.3
  • Cheap Chinese KKL 409.1 cable with pin selector switches
  • Using pin 3 as required for the ECU K-line
  • I can also switch it to pin 7, but ECU communication is supposed to be through pin 3
  • KKL chip is marked FT232R
  • Using FTDI drivers on a clean windows 7 machine with the required net framework

P80 3rd Row Seats

I have been looking high and low for the 3rd row seats to install into my 97 850 wagon. Does anyone have any for sale or know where I can get them? I will need to purchase the complete set as my car did not come with them.
Also looking for the roof rack rails that bolt onto the top of the car as well since I have a base model.

Won’t start when hot

Weird issue with my 96 NA. Starts for the first time of the day (when motor is cold) instantly every day with no issue. Runs great with no trouble, no weirdness. Temp gauge warms up as expected and stays pinned in the center.

If I try to start it a second time in the day after the motor is even remotely still warm (sitting for hours), I get crank but no start. Used to fire up eventually after 10 seconds or so of continuous crank but now no dice. I recently found that if I floor the accelerator while cranking it will eventually fire up (see video). Once running it’s perfect, no issues, no variation in idle, totally sound.

I’ve seen information that says the ECT sensor is likely to cause this, but that issue also typically displays issues with temperature readings and mine reads perfectly normal on the dash and on my OBD scanner. Maybe there’s something I’m missing, has anyone had an issue similar to this or have advice on what to check? Thank you! :)

I keep thinking of getting something newer and more practical...

...but then I step on the gas and hear that 5 cyl growl, look down at the dash, and realize there's no other car I'd want.

Got new brakes and rotors in March. Now my brakes are squealing heavily and shedding a lot of brake dust

‘97 850. Tried googling but getting different answers. It’s well past the break in period, I’ve put about 2,000 miles on it. Had it replaced in March by a Volvo speciality shop that says they use genuine OEM parts.

The brake dust seems to be excessive only on the front wheels but still a decent amount shedding in the rear

Any idea what it could be and if I could fix it on my own before I take it to the shop again and see what’s up with it? Not too mechanically inclined but if it’s an easy enough fix, but I want to learn how to work on this car and I’d rather save time and money and do it myself.

J&R - any good?

So whilst my car passed its MOT with barely a mile on after a lengthy rebuild - the work started 6 years ago during COVID. One job I did was new CV joints and gaiters but annoyingly, the rubbers are already perished even sat motionless (albeit for 6 years!). No idea what parts I used but I hate doing gaiters, it’s so messy. Quick look for gaiters and noticed whole shafts aren’t silly money. Quicker turn around and less messy.

But these seem VERY cheap… anyone any experience with these units before I make a mistake. Also - I don’t see many options for sale - where would you source shafts / gaiters in the UK?

Thanks 😊

Looking for Interior colour code

Hi Lads,

New to the 850 scene just picked up this 1996 volvo 850 T5, I am wondering if anyone is a wizard in this area on finding out what the actual colours are. My engine bay plate tells me 3930 which just says 'blue'. I have some trim pieces I would like to 3D print and would like to try find filament as close to the correct colour as I can

Brake squeal

Hey folks - recently recommissioned my 850 T5 and having annoying issues with brake squeal. Turns out I had a seized caliper at the rear so have replaced both and put in new pads and fitting kit (per the picture) and I think I’ve mainly solved the squeal from the rears but it does come back from time to time.
I seem to recall their used to be anti-squeal shims available that covered half the pad but I can’t find them for sale anywhere anymore!

I also have squealing from the fronts so all the slider pins are coming out this week for a refresh / replace to try and resolve that issue.

Anyone else chasing squeaky brakes??

Cluster lighting going out

Is there a common reason my cluster lights would turn on with the headlights but then turn off again after a couple of seconds like I flipped a switch?

I haven't checked anything yet I'm just hoping there's something specific that might cause the problem, I don't want to have to go chasing all the connections to find a bad ground or something like that because I don't have a wiring diagram or the patience for elecronics

I imagine there is a chance it's a voltage issue, the car hadn't run in about 4 years when I bought it and I haven't put a new battery in it yet but I doubt it because the issue doesn't go away when the car is running

It's a 96 850 TDI with the 'CD' trim level if that makes any difference

Radiator leaking?

hi! It looks like i have a coolant leak coming from this hose connection. LHD on the passenger side. Is there a seal in there that might me gone or is it the connection? I have checked the bigger hose above it, and that all looks good no cracks or anything.

Import from Japan

I have become a father and therefore I think it is finally time to let go of my infinite mileage 850 turbo as I do not have the time to tinker on it anymore. I am thinking I should do the whole Japan import as its the same price for something that is in much better shape. I am looking at a xc70 2005-2007. Does anyone know what is the best website/method to go about this?
