Sorry to hear all of this Mike :( Just goes to support my belief that modern cars are just too complex for their own good...

Yes, designed to put money in the manufacturers pockets?

New turbo cooling pump fitted today. Having seen a video showing how replacement is done on a mini, I can say that access is much better on the 308, it can be done from above, and if you squint at the right angle, you can just about see the mounting bolts.

The pump comes with attached mounting bracket, but there must be two versions of this assembly, as the supplied bracket was bent slightly differently to the original and hit the transmission. Perhaps the are different for auto and manual? I swapped the new pump onto the old bracket and all is well.

The fault codes are all gone and I can hear the pump running after switching off the engine. I never noticed it before, perhaps it has been faulty for a while, perhaps the new one is just noisier.

Excellent stuff Mike :D Lets hope now a period of reliability and trouble-free running will be experienced...

Glad you've managed a fix. One more for the naughty and no-no list, and another example of Peu treating customers with contempt.
Toyota would either have done a recall, or simply put the offending part on massively extended warranty, which is one good way of managing the situation.

If I lived a bit closer, Jim, I'd come over and thwack its bonnet with some birch twigs.

Since having the inlet valves cleaned and the PCV bypass and oil vapour separator, we have been quietly using the car, mostly just around town.

The power surging when on boost, which went away when the valves were cleaned has gradually returned, and for the last couple of weeks the engine has thrown an error code when on boost.

Yesterday I connected up diagbox and read the fault codes, and found as well as the recurring knock and super knock errors, a p2263 which is a turbo over-boost error, which on reading around seems to be most likely to be a sticky boost control valve 1922V6. This would explain the surging, and would probably mean that the previous carbon clean was unnecessary.

I will see if I can get a replacement electro valve locally at a fair price. Unfortunately it seems that the BWM/Mini variants of this engine use a slightly different electro valve, so that source of parts seems to be closed.

The bigger worry is the task of getting to the faulty valve. although it only connects to the engine via vacuum and electrical lines, it has been sited at the rear of the engine below the inlet manifold, and access seems to be impossible. I cant even find a good description of the job on the internet. I suspect that the manifold needs to come off, which is a 4 spanner job itself.

So that is the immediate problem...

My brother ended up trading in his 207 GTi and getting his fiancé a DS3 1.6 HDi DSport Plus to replace it.

I can't say we were sorry to see the back of it. The car was great, suspension, seats, appearance etc, but that THP engine was badly flawed by design.

A few months ago I deleted the rear PCV hose on the engine and fitted a vapour seporator and catch tank in the front PCV hose. In the first 200 km the catch tank collected a little oil (less than 1 cc) and on checking the level every few weeks, it did not increase for the next 2500 km. Now, in the last 2 weeks and 500 km the catch tank has suddenly caught about 10 cc of oil.

I am at a loss to explain the sudden change in behaviour, perhaps it is linked the the over-boost fault, but I think that the boost control valve has been gradually failing for some time.

I am in any case glad that the oil has not gone back through the engine.

Mike

It only books at 0.7h in the C4, so it can't be that hard, can it....??? Access from underneath. Here's the text, I'll e-mail you the PDF with the pics in. The valve is 'only' £66.50 in the UK, and could probably be got cheaper from the dealer in Preston. Let me know if you want me to get one and send it over - I doubt it is heavy.

1. Location

Figure : b1hg45ed

(1) Turbocharger pressure regulation solenoid valve.
2. Removing
ESSENTIAL : Before starting any operation close to the exhaust line, wait the latter to cool down.
Disconnect the ancillaries battery .
Put the vehicle on a hoist.
Remove :
The protective panel under the engine
The exhaust hose

Figure : b1hg45fd

Remove the nut (4).
Move aside the starter supply cable (3).
Detach the turbocharger pressure regulation solenoid valve (1) from its support (2) (at "a").
Disconnect the connector (at "b").
Unclip the pipe at "c".

Figure : b1hg45gd

Uncouple :
The pipe (7) (To cylinder head cover breather)
The pipe (6) (To turbocharging pressure regulation solenoid valve)
The pipe (5) (To vacuum reserve)
Remove the turbocharger pressure regulation solenoid valve (1).
3. Refitting
Refit the turbocharger pressure regulation solenoid valve (1).
Couple up :
The pipe (7) (To cylinder head cover breather)
The pipe (6) (To turbocharging pressure regulation solenoid valve)
The pipe (5) (To vacuum reserve)
Connect the connector (at "b").
Put the turbocharger pressure regulation solenoid valve (1) in place on its support (2) (at "a").
Clip the pipe (6) (at "c").
Refit :
The nut (4)
The starter supply cable (3)
The exhaust hose
The protective panel under the engine
CAUTION : Perform the operations that are required following a reconnection of the ancillaries battery.
Reconnect the ancillaries battery .

Thanks for that, the (few) other references I have seen say that there is no access from below, and it has to be done from the top. I will put the car on stands and see if I can see the valve.
