Hi All, After 8 years of 240 ownership and multiple 240 rescues along the way I've upgraded to an 850 T-5R. Big drive home from NSW yesterday but it gave m...

I remember someone on here brute forced a radio code with a bench power supply and patience, I think it was @Major Ledfoot

jamesinc yeah, I read this thread today. That's an insane amount of time and patience 😳

The actuator should be set at around 4psi, the tcv will control boost after that, that's the way it's designed and mapped in the ECU

morch_66479

Jamest5r_ where did you get this info from as I read it was meant to be 1.8psi.

Also of I adjust it to 4psi what differences should I see? Later boost, more boost, lag?

Depths of my memory, had my T5R for 18yrs and many many tuning stages, I could be wrong though, the 1.8psi your thinking of was for the low pressure turbo I believe, again I could be wrong

I'm sure I've got an 801 cassette player in the shed , I'll look after work .

Ahh mine is a 810 not the 801

Does come with code and the manual though

Any idea if this particular model came in the 850 T-5R. I guess I'm just chasing the original radio that would have come in it from factory but there seems to be so many different models.

TBH I'm not sure what HU was in the T5R .

Jamest5r_ I was speaking with VP TUNING today and he said it should be 1.8psi so I'll go with that for now.

If yours was a Jap import then the radio in it won't work correctly here in OZ. The Jap frequencies are lower. I have an 850R import and had to change to a OZ imported version. You can also get the code from your Volvo dealer as the original Jap import radio came in a box with the car (it had an aftermarket one in it) and my local Volvo dealer sourced the code for me.

dmcoz So the radio i purchased with no code is from Europe but unfortunately can't get the unlock code through Volvo Aus :-/
The current 850R radio is for the Aus market so all works perfectly.

PAINT:

Over the past few months I've been noting all the little stone hips and places that need touching up. I've also managed to get my hands on the headlight trims for the headlight wiper kit I'll be installing on the car any day now.

All of these needed paint so i sourced a very good paint match from Complete Auto paints of Springvale. Turns out you can get a 2 pack rattle can. I never knew this existed until last week.
The paint mixture took a few modifications, back and forth to my car to inspect colour match.

Colour matching

2 pack heated in welding rod cabinet before use.

Trims keyed with 800 grit and prep washed

3 coats of paint applied and baked at 60c for 45 mins, left to cool for 20 mins.

Finish and colour match comparison. Not bad for a rattle can.

The can advised to use within 8 hours of piercing the diagram and the paint mixing within the can. However, I used the can the following day and do touch ups around the entire car.
Headlight kit to be installed any day now!! :-)

How did you go with the fumes, did you wear a respirator? I'm going to try some 2K aerosol on some repairs on my 244 soon.
