My woes continue with the new ride Superb 2 DSG 170 2011 88k. 5 days of no driving took it to work having topped up £10 of Shell standard derv. (See other thread about my requirements for range). Trek is 95 miles at 6am. 6.5 degrees on temperature gauge most of trip today.
The car stats into the journey.
oil temp 70 as does the temp gauge say the same. Again this should have reached 90 like it usually does well before this. Has done this before with some coolant low issues(another thread) that's fine now too.
Anyway 85 miles into journey of gently 70ish cruising I have to slow down for traffic and the glow plug light is flashing and I then notice when accelerating there is a distinct lack of turbo boost. I think this is defianately limp mode. Anyway continued off the motorway at the next junction and into the work car park. Light still flashing no other warnings.
Having read around the net and Briskoda there is a exhaust sensor fault and perhaps other things, like a DSG temperature sensor for the needle issue ?
I am now deeply suspicious that the low temperature and my sedate albeit motorway speed driving today could have been the cause of this ?
Restarting it at work no warning this morning.
Fast forward to 16.30 journey home. Outside temperature 22 according to car. It's up to the 90 on the needle after about 5-10 miles. Decide to drive it in sport a little and run it at 3.5k revs for a mile in a low gear. All the way home mixture of driving motorway sport mode/ drive mode. Stop start traffic. No issues whatsoever ever.
Refueled before parking up at 18.40. Perfect.
Tried to use my simple code reader. Refuses to read the engine code and abs. Airbag ok. Thought I may as well check everything.
So in the absence of a code reader. What am I looking at here ?
Have been running my 2014 184ps with the CRD-t+ box for past 18 months and great performance and consumption but about 8 months ago started getting occasional limp mode happening. Has been reset and then goes months with no problem then kicks in again. Finally tonight it has happened multiple times on way home reset codes but soon as I accelerate hard it comes back again. Engine revs fluctuating and engine making clanking noise. Currently running box on settings 3+3 as had too much turbo lag on 3+1 & 3+2. Took the box off and reset codes and now running fine.
Has anyone else experienced this as kind of points to box?
hi guys tried using the search bar but nothing much has matched my problem.
has my 170cr vrs for nearly a year now and its been pretty trouble free apart from a new egr valve and throttle actuator about 6 months ago.
until a few weeks ago i was on the motorway and went to overtake and the poke that is usually there was absent. eventually the engine management light and glow plug light came on with the following codes :
the codes are for under boost and fuel system too rich i think?
if i go anywhere near the throttle aggressively plumes of black smoke comes out and i only really start shifting past 3000rpm. the smoke is enough for other motorists to slow down! up to 2000 revs there is no smoke but the car is very sluggish its defiantly in limp mode. the turbo seems to spooling up fine and there are no audible boost leaks but it just isn't 'pushing' the car along? i dumped a can of MAF/EGR engine cleaner in it the other day and still no improvement. if its any help my car has been remapped by shark performance and has had its DPF deleted, i have had no problems with the map.
can anybody point me in the right direction or perhaps let me know if they have had this problem before? thanks in advance!
