No "turbo boost"

[Sooty torques]

Yeah, I know that some folks on here have had problems with Premier @ Leek, but they are always straight (? I hope?) with me, unlike others around here... i.e. last service I forgot to book it in, short on time so went to Willoughby's at Chilwell (more local) - tried to talk me into having new pads and discs on the back @ 48K, said they were corroded and worn... and why not have the front done while we're at it? (only £350-odd + VAT, Sir!). Premier had a look at them today and said they're fine (looked it to me too!).

Anyway, getting back to the topic the MAF was £64.00 for the exchange unit and they charged me £18 for fitting it (all plus VAT of course). One of the fault codes listed was 17964 - whatever that is...

Update. Covered about 200 miles since the new MAF was fitted, including towing my caravan and my mum's, and everything is groovy so far. MPG is up (been down from the norm for a few months) and power is definitely up.

I reckon that the MAF must have been on the downward slope for some time; like a new car again.

good to hear Ray.

Had a problem with no boost yesterday evening.

Car is reported (by my better half) as having a whooshing noise, smells hot and stalls repeatedly - shes made into the supermarket and parked up having driven the car about 800yds. Lots of grey smoke from exhaust, but no engine check light.

Turns out that the pipe from Turbo down to the air intake (?) on the lower RHSide of the car bumper has come adrift. Getting the car up and putting the car on full RH lock allows you to get into the joint (inside wheelarch). Once this was all put back together with zippies the car was A1 again, boost /power/torque came back. (will be going back to fit a Jubilee clip this weekend as belt and braces)

Car is a 110TDi Leon.

Really new to Cupra.net, so not even sure what the pipe was (as Air Intake/cleaner appears to be on otherside of car). Can anyone help identify what it was I fixed? rolleyes

Just seen the post from SSSTew. You've another Mini Nut on here brother

It will be one of the boost carrying pipes. its not unheard of for this to happen. replacing with a decent clip like you said will be fine.

Dragging up an old-ish thread...

So, hoped the new MAF had sorted my problems...

First day of holiday. Get off the ferry in Dunkerque, zip down through St Omer, pick up the fast road to Boulogne and up-pops the warning light, down goes the power Over 1,200 miles to go to in-laws in Spain and I'm being overtaken by lorries and 2CV's!!!

By hit or miss, worked out that by switching off and letting the engine cool for 15 mins or so, would bring the power back but not lose the warning light. Those autoroutes in France have some good hills on them so every time we hit one, -pop- power would go. If it was a straight-ish run down the other side, turning the engine off for as long as possible (not recommended!) and then on again would restore power, but engine was flat to 2K - then bedlam. So we limped through France, crawled over the Millau bridge and coasted down to the south coast. The autoroute along the Med is quite flat so no heavy load on the engine, so after Beziers no more loss of power... As we trundled along the A7 in Spain towards Castillon, the warning light also went off...

Luckily in town where in-laws live is a new SEAT dealership, so with the aid of an ex-pat who spoke really good Spanish, we took the car in. My reasoning was that if anyone should be able to sort a Diesel out, the Spanish should, seeing as DERV is cheap (< 70p a litre) and TDI's outsell petrol by a significant factor... The Service manager was very efficient and within a few words of explanation said he had a good idea what the problem was, and managed to squeeze us in as an urgent job. Warned us that it could be expensive though .

Day after taking car in, phoned to say their assumption was correct and that the turbo needed removing from car, dismantling and everything needed cleaning out; said it was a common problem with the PD motors and was surprised that the English dealers hadn't spotted this? Needed my ok to continue due to the cost involved

Then he said the quote for the work was about 320 euros...
Now that's about £215!!! He was very apologetic about the cost...

Anyway, two days later goes to pick the car up, total bill is 314.16 euros, which included 8 euros for a container of cleaning fluid - and 30 euros (£20) for the diagnostic; I'd just paid £64 for a diagnostic in the uk!!! Got a two-year pan-european warranty on all their work, valid at any SEAT dealer and all the paperwork and print-outs were placed in a nice little wallet which included the photo-id business cards of the people I'd dealt with! My only gripe about their work was that they managed to scratch the shiny SEAT badge on the engine cover, but that will Brasso out.

So we set off up into the mountains for a bit of enthusiastic driving to see if they'd fixed it and now back home and nearly 2K miles later (including a very exciting journey up and over the Pyrenees), the engine is whistling and humming like new and no problems to report. Really pulls from low rpm and right through the rev range.

So, future holidays are likely to coincide with servicing... Cam-belt is coming up, as are discs and pads all round...

sounds like a good price, and very good service. glad you got it sorted Ray.

I have a similar issue that my car goes into limp mode up only a slight gradient at the end of fourth gear or in 5th gear. Might get the turbo looked at if it could be that! Dont want it getting worse.

That is just how mine started - hot engine, under load (5th or 6th in cruise, uphill, or when towing the 'van). At its worse in France near the Millau bridge, it would go into limp on the slip-road gradient!

Be aware that it is a costly job in the uk at a stealers - my usual one quoted me around £600 to remove, dismantle and clean the turbo and then put it all back... As you can see, paid a third of this in Spain. DIY job or an independant? Deffo try shopping around with Skoda and VW places to get the best price.

Sounds like it was the VNT mechanism on the turbo that sticking causing the turbo to overboost hence sending the engine into limp mode. As the spanish dealer said this is a very common fault and should have been spooted by your dealer here in the UK. Although it was an expensive fix it sounds like you got excellent service from the spanish dealer and hopefully you can put this problem to bed finally.

So we limped through France,

The analysis -- sticky vanes or a bad VNT actuator -- is probably reasonable for this and nearly all similar limp-mode episodes. The ECM is putting the car into limp mode to protect the turbo.

You might be able to avoid or reduce these episodes by keeping the revs up -- so downshift on those hills even though you don't think you should have to. 2500+ RPM should be high enough.

If you do experience limp mode, just push in the clutch and do a quick restart -- no need to let things cool down for 15 minutes or any length of time.
