longshot – Anyone a mechanic or knows about the Vauxhall CDTI engine?
The engine light comes on and it feels like it's lost most of it's power I.e. Going 70mph on the motor way to struggling to keep at 40/50mph. As soon as the engine is turned off and re started (without stopping sometimes) it's back and working perfectly.
Only reason I want to get it sorted is I don't want it to happen to the GF on the motorway. Otherwise I'd live with it as it's so intermittent.Posted 7 years ago
EGR valve – get one on ebay and fit it yourself – 4 bolts piece of piss.
All in < £100
I thought about doing that. I couldn't locate where the EGR valve was though (I was going to clean int/disconnect it to see if I could fault find)
No matter how many Internet searches I couldn't work out where it is!!Posted 7 years agomountainlightMember
Agree with everyone else – worth the money to get the faults codes read out – local garage should do it for 40 quid or less, but at least you'll get a good pointer on the problem.
Not sure on EGR failure – it's mainly an emissions component, so should light the MIL, but not cause engine torque limitation. Torque limitation would normally be for a failure that could lead to engine damage (head temp, oil temp, turbo related – MAF, MAP), or safety (pedal position).Posted 7 years ago
For the past few weeks our 'bike only' transporter has started to go into limp mode every so often when i'm in the higher revs (above 3.5k)
It did it about 6 mts ago on 1 occasion but has been perfect up until a month or so ago.
Last weekend we managed a 150 mile round trip to Dalby without issue but yesterday it did it within 10 mins.
Its a 2005 Combo 1.3 CDTI with 60k on the clock
Any help appreciated.Posted 7 years agocarbon337Member
My egr valve did this on a 1.9cdti – spanner light on and it goes into limp mode… no torgue as if you can barely get over 30mph.Posted 7 years agomikey-simmoSubscriber
I'v got a 1.7 ctdi honda civic, common rail engine went into limp home mode when you went for more revs' overtaking puling away from junctions. Eventually i found it was fuel starvation to the common rail resulting in reduced power to get you home and then to the engine being cut out.Posted 7 years ago
I replaced the fuel filter and everything since then has been great, apart from the honda and the civic bit obviously. Cheap fix though.cabeaumontMember
i had an Astra 888 which had the 1.9cdti engine. had many occurances of the problem you have described and, as many other have said, it was egr valve each time….apart from the last time I had the problem which turned out to be the inlet manifold…..this was last straw so sold it!
Might be worth having a look on Astra Owners Network Forum to see if there is anyone around you with tech2 system that can plug the car in and confirm that it is egr valve.
Hope you get it sorted!Posted 7 years agoMrGrimMember
If you've got breakdown cover then call them out just after it happens and see if they can read the code. I did this when my Passat kept going into limp mode and they (local garage via green flag) managed to retrieve the code and diagnose. Might be worth a shot as won't cost you anything.Posted 7 years agoseizednutsMember
Its worth taking it to a main dealer for diagnostic. Their can be fault codes present that are brought on buy other faults.
In short, the computer might say EGR valve fault but it could be a faulty sensor or a split vaccum pipe.
You could go down the bolt it on and see route, you could get lucky. Can get expensive if you get it wrong.
Main dealrs can be expensive but usualy they'll get it right.
Normaly you'd get charged 1hr labour for diagnostic, You dont have to get them to rectify it.Posted 7 years agoPeteG55Subscriber
I believe EGR valve and cam pos sensors are favourites on these engines. Disconnecting the EGR valve should put it into limp home mode full time, as will cam position sensor. If you can locate the EGR valve, best off try that first, cleaning it up with some brake cleaner or similar and refitting. They get gummed up for a past time on lots of cars.Posted 7 years agomarkyboyMember
spanner light and loss of power is quite often throttle potentiometer(if fitted to this model)which it should be.it is part of the throttle pedal.it is worth disconecting multiplug and reconnecting.
if spanner light is on it is not an emissions related fault as this should put on engine management light.Posted 7 years ago-Liam-Member
You might be able to find out what the fault is without paying the garage for diagnostics – see the third post here for details. There's also a list of common fault codes on that page
That list is a list of codes for slightly older cars, such as the old vectra. You could simply short out a couple of connections on the diagnostics port with eachother using a paperclip and using the ecu light on the dash, discover the code and find the fault from that list. The newer engines with the canbus electronics arent so susceptible to the same sort of diagnosis. You can only discover the codes if you know someone with access to op-com or tech2 software on a laptop or just go and buy it yourself..
It works absolutely fine so long as you have a laptop 😀Posted 7 years ago
got one in today and its waste gate is siezed shut causing over boost. Then the ecu kicks in and stops the power being produced. Fairly easy to check for under the front of the car using a small lever bar or a pressure pump. If you take the car to a garage suggest they check this first. It comes as part of the turbo but turbo prices are very cheap for this engine . I wouldnt even try to free it off unless it was my own car.Posted 7 years ago
Oxnopp what would you say your driving style is ?
I've had similar problems on various Vws in th past and there's an easy fix.
Depends, it a second vehicle only used for MTB duties. SO it can be used 3 or 4 times in a week or not at all.
Both the GF & myself drive it, so mixed driving style. I have a new Golf GTI which I tend to drive in a spirited fashion so the van gets an easy life!

As part only what is reasonable for a turbo replacement on this vehicle?Posted 7 years ago
