I have had exactly the same thing happen to me. In the end it was a faulty water pump which was allowing water into the engine.

I had the same problem with my T5 130. My mechanic replaced the head gasket to no avail,then we checked the oil filter,that was ok.then we went on to a web forum and found out that the AXD engine suffers from water pump failure.We took it off and it was corroded,the seal had failed and was pumping water into the block.My advice,CHECK WATER PUMP FIRST! Good luck Marc,Somerset.

SOURCE: 2001 volvo s60 t5 - performance reduced warning message, limp mode activated

I had exactly the same problem on my UK 2001 S60.
It was caused by the throttle control housing gaskets not being serviced properly and consequently the entire housing had to be replaced - not a cheap job -and a valuable lesson learned - use a reputable volvo specialist to service your volvo - I didn't and I learnt the hard why! only a volvo specilaist would have known about this I went to several other main street garages & none of them could even diagnose the problem let alone fix it. Although they did do numerous other things first before they gave up - ie replaced titanium spark plugs.
Before it stoppped running altogther and went into "limp home mode" there were tell-tale engine/throttle surges when the car was idle, but in gear.
It is now running "like new" & I will never get another garage to service it, as this could have been avoided - however they can also wear out after about 10years - so my bad services just made it happen sooner!
I hope this helps!

I believe this is the warning for your front brake pads being worn.

I have Ford Focus 1.0 EcoBoost 2012. I have experienced an intermittent problem where I get a loss of power (turbo not working)and car goes into "limp" mode. No warning light appears and the car


thats sounds like a possible boost control solenoid failure.when the boost solenoid fails it wont activate a warning light and because of the lack of boost the engine computer fail safe feature will put it in limp mode in order to keep the driver from harming the engine

VW 2004 T5 MULTIVAN, DIESEL, 2.5, 170PS -- Can't find cause of Limp Mode


You put it in park and turn off and it resets. You turn it on and it runs awhile and zeros out. Try looking at the parking sensors and the on board computer.

Faulty Turbo


Now if i knew what you meant by blew ?? then i might have a idea --most turbo faults are caused by dirty oil and changing the engine oil every 5000miles with a filter every third oil change will stop this problem .The other problem is the turbine vanes breaking off or being damaged by grit where the air filter is missing or a pipe loose or split allowing the thing to suck in unfiltered air but i do know someone with one of these and he sold it in the end and bought a transit as the turbo gave up quite often ,but without taking the turbo apart then i couldnt tell you why they are failing but i do know he kept a small hand held diagnostic machine in the cab and when it went into limp mode he cleared the codes and off he went again .Seem to remember as well the waste gate operating piston playing up i think a rubber tube perished so it didnt open and the increase in pressure as the engine revved up caused the thing to go into limp mode as too much pressure was being generated ,the rubber tube goes from the pressure side of the turbo to the piston its about 4cms long so as the air pressure builds up it this pressure pushes the piston which opens the waste gate which is a little flap on the exhaust side of the turbo into the exhaust manifold so when it opens it allows the exhaust gas pressure to go straight down the exhaust pipe releaving pressure on the turbo vanes .If the pressure in the inlet side goes too high then a sensor will put the engine into limp mode .Hope you understand this technical jargon ?

My 2006 2.0 tdi passat keeps going in limp mode and saying emissions workshop. Can anybody help


hi mate, my 55 plate passat did the same before major problems happened. first turbo went then the oil pressure light came on and the car went into limp mode. before its too late for you and a costly bill can you do the following.
check if your car has a recall for the injector problems which vw are replacing under warenty.
second thing the guy who repaired my turbo told me that these cares have a major fault which caused the turbo to go. the fault is the oil pump failure you must adress this issue as you can get a lot of info on the discussion forms.
my car started with the same problem as you have described the pd engines have a design fault with the oil pump and shaft. this is common causing your turbo to go then the car will start showing oil pressure low please stop engine. educate your self via the forms and act quickly befor you end up with massive bills.
i hope this has helped. trust me vw know about this design fault.you need to change your chain driven oil pump to the new gear driven system which vw have modified. all vag cars have the same problems be it audi skoda vw . my car had the same problem as you have said .started off with emissions then turbo failed thats when i started to investigate this problem . the pd engines was designed by some rookie at vw.

Lack of power


Turbo failure is never normally intermittant so I doubt it is a turbo fault.

The wastegate relys on a signal from the ECU via the MAFS.

Mass Air Flow Sensors are very common to fail on VW TDi and this also fits in with your symptoms.

Kind regards

VW transporter power problem


Hi nick. I have a T5 04 model and recently had the same problem. i was told it was a blown turbo so i had a friend look at it and turbo was fine. got vw to run a diagnostics and it had a broken wire running from the charge pressure meter. replaced for 9 euro. 3 weeks later same problem and it turned out to be a loose plug on the air mass meter. now its perfect again. apparently what happens is that if the engin management is getting a wrong reading from the pressure meter it limits the van to 40 horse power for fear of blowing the engine. whenever i switched the van off and back on the problem would fix itself but as time went on it got worse until complete failure. the wire is located under the coolant resivoir. dont know exactly where though. email me on paulblackpb@gmail.com if you need to know more. if it does turn out to be the turbo (which i doubt) then there is a website called CRTurbos that seem to be the cheapest around. but i seen another forum where the turbos were replaced and the problem remained. I suggest first look at the charge pressure meter.

LIMP MODE


You will have to have the fault codes read and removed. If it is permanently in limp mode it may suggest another problem.
