You didn't mention RPM or acceleration feel. Boost is a restriction to airflow. The more airflow (to the engine) you have, the less boost is captured at the manifold. When the charged air is consumed...

The dirty cylinder walls (1,2,3) could be stuck oil rings on the pistons. Was the car smoking prior to this ? Did you get alot of blow-by ? What boost were you running ?

The TCV is always open (from turbo compressor snail to wastegate) unless the ECU fires some PWM voltage to hold boost. As mentioned 100% DC is fully closed and 0% is fully open.

Now on the...

Get a medium size syringe, plug it parallel to a boost meter with the actuator hose.
When pressuring the syringe, see if there is movement on the actuator, in comparisson to the boost meter. Some...

If you go through your local agent, remind them to specifically remove the rev-limiter as your auto wiring loom will have the P&P switch fixed at neutral/park, so your car can start. At these two...

You can contact RICA as they did a software for XC70 auto using a s60r engine (manual) for me. The ECU is still the xc70 but map has been converted for the manual.

Did you check your fuel pump ?
It's not broken (since you can start it) but the petrol hose inside could have shrunk & leak back into the tank, and the motor feeding fuel to the upper (fuel pump)...

Some pins on the ECU could be loose (poor contact) and after pulling and re-inserting the ECU, the contact came clean. Another area will be the ECU is limping but MIL is not on yet.

Check if yours is an AW50-42 or AW55-50. Both can be repaired, you just need to get the right guy to do it.

You might need to switch some wires at the OBD port in order for the generic readers to work.
The K-line is not in the right places.
Now.... where did I put my schematics.

Hey good to know it's back on the road. Mind telling how much it set you back ?
It's true you wouldn't know what condition the donor units will be and yo might be back to square one.
That's why I...

On each individual exhaust outlet, the gases are coming out in pulses, not a continuous flow of air (unlike the intake manifold). Give me some time and I'll calculate the amount of exhaust...

You drive too slow ... :D
Carbon build-ups and you just need an italian tune-up

Fuel sender won't give you this problem. If it's serious enough, then you get a CEL.
When was the last time the air-filter has been checked ?
Is the BCs/TCV knackered ?
Last but not least, a...

If there's no communication to the ECM, it's the ECM itself.
I've repaired a few units for a small fee but I'm a great distance from you guys, so that's out of the equation.
You can take a CEM, ECM...

You may be running too rich at the low RPM range.
Use the guide below to tune your fuel table

To remove the strap, use a saw blade to make a groove on the rounded rivet-like fastener. With the groove done, just use a "minus" screwdriver to remove the fastener (recycle it). The ECM (sitting in...

You'll need a hot air station for the M4.4.
Been there, done that but for the novice, get a mobile phone repairer to get it out for you

I would use the original Volvo disc with Ferrodos / Carbotech

Check out brickboard (or something similar) which shows you can't fit one in the older models unless you want to run the post turbo hose downwards. You have to put the hot side on the passenger side...

Use an addidtional vacuum pump like the S60/s80 where a pressure switch will turn the vaccum motor on where there's a lack of vaccum in the servo or go hydraulic (like me) :D

1st: Brickman, you need to use paragraphs :D
2nd : Someone did ask me to assemble an eBay chip for him and from my experience, it'll work with a 15G. But put a 18T/19T inside and you'll have boost...

The vaccum/boost is coming from the intake manifold (Christmas tree) near the throttle body.
Look out for the white plastic hose, it'll lead through the firewall, underneath the steering coloumn and...

Your original hose to the actuator could be leaking and thus the force to push the wastegate was reduced, giving you more boost. Sort of like an MBC. When you renewed the hose, every bit of pressure...

Lambda lamp is the yelllow triangle outline by green (or the other way round). It has a roman character inside which is the lambda sign. When the engine doesn't catch, it could be the immo, main...
