Loss of Power :/

[47p2]

It's a list of what you could easily check without throwing a lot of money at the problem. You really need to get the car plugged into VCDS and have a scan done so that you can pinpoint the fault. Generic OBD code readers don't give enough information

I understand. Is there anyone near Birmingham with VCDS?

My garage has just his OBD system

Thanks, I dropped Singh a message, as he is the nearest person to me.

Presumably the easiest to diagnose would be the turbo issues.

Can you recommend any other thing to look for in terms of symptoms? Can we be 100% sure it's not the DPF at this point?

And finally, what about the movement in temperature at motorway speeds...

Just a note to say thanks guys for all your input, I really appreciate the community help!

Just a side note - not sure if its an update or more of an observation.

Checked all the fuses, all were okay (on both sides).

However, I lifted the bonnet and powered off the car, and noticed a clicking noise. Almost like an open/shut valve of some kind. It went on and off about 3 or 4 times, then closed.

I don't know what it is or if it was there before, but then even when I turn the ignition on, and not the engine, then switch it off - the same clicking noise is present.

It's similar to this:

The engine being so loud, I don't know if its doing it while in operation, but it's definitely doing it when I switch everything off. Is this normal behaviour or could it be a signal?

Turbo sounds likely. Best thing to do is clear the codes and see if they come back as the machine on the photo doesn't seem to show when they started to ocurr and how often. Maybe it was a fluke 6 months ago and therefore a red herring.

Unbeknown to me, I had a blocked DPF when I bought the car.
Some buffoon (probably the selling garage) had done a software DPF delete, and then hollowed-out the catalytic converter instead of the DPF.

It was fine when I test drove and on the way home from Birmingham to Nottingham.
The symptoms were not bad when first setting off first thing with cold engine but progressive loss of power as it warmed up.
It also ran hotter, not colder.
After a week, the turbo centre gasket blew due to the back pressure so I put a new £800 turbo on thinking that was the problem, still no power.

It took a while to find it was the DPF and another £400 later all sorted by removing the DPF and finding it chockablock with soot.

Luckily I bought the car for a great price and the dealer went bust a few days later.

Maybe your second thermostat beside the autobox is stuck open. There is a thread somewhere, and it's a £20 fix.
When you get some air through the radiator it soon pulls the temp down with this stat open.

I understand, I'll follow up on that thermostat problem ASAP as its a simple fix.

To be honest, I'm hoping it's not the turbo as thats going to cost a chunk!!

If it's just a controller or DPF needs some work, then that should be fine I'd assume (in cost comparison to an entirely new turbo!)

I was going to remove the DPF, but I'd be terribly upset should it not be the issue, and then have wasted that money that could've gone to something else. It's heartbreaking

I forgot to mention - when those codes are cleared, they instantly come back on when the engine is started.

Anyone?
