Check Eng, ESP Fault then LIMP mode after a workshop jump started my S6......

A6 All/ S6 All

Hey Guys,

The Workshop that was tickling up my wheel alignment flattened the batt enough they had to jump start the car (found this out after I range them after the lights came on etc) when I picked the car up the Eng light was on, 2 min later the ESP warning came up saying “check owners manual” - then then the car went into a progressive limp mode driving ok at 30MPH but struggled to do 60…

I found one fuse (20Amp) in the rear tunk fuse compartment blown which I changed out, now the ESP warning does not appear but the eng light and limp mode remains on…Im off to get her scanned this morning. Will post codes when I can

Q1 - is it normal for the eng light to pop on after a jump/flattened battery?
Q2 - this limp mode is the major concern, the car literally struggles to go up a hill at 50MPH - im picking its a safety feature - should this clear post a VAG COM clearance of the check eng light?
Q3 - can things be broken/blown from a jump start…?

The car runs, sounds 100% fine until you try and drive the thing…no misses no coughs - just runing at about 15% total power!

So after a couple hours of scanning and fault finding the big hitters are

Address 7E8: 4 Faults Found:
P2088 - Bank 1 Camshaft A (Intake) Position Actuator: Short to Ground
P2090 - Bank 1 Camshaft B (Exhaust) Position Actuator: Short to Ground
P0661 - Intake Manifold Tuning Valve Control Circuit (Bank 1): Short to GND
P2009 - Intake Manifold Flap; Bank 1: Short to Ground

Address 7EA: 2 Faults Found:
P2092 - Bank 2 Camshaft A (Intake) Position Actuator: Short to Ground
P2094 - Bank 2 Camshaft B (Exhaust) Position Actuator: Short to Ground

We found that a 10A Fuse in the front left on the engine bay under the ECUs keeps popping on Engine start -

this fuse protects/is attributed to:
N205 Camshaft Adjustment Valve 1 and N208 Camshaft Adjustment valve 2,
Camshaft Adjustment valve 1 (exhaust) and N319 Valve 2,
F265 Map controlled engine cooling thermostate,
V157 Intake flap motor (BXA) and V183 Variable Intake manifold runner motor (BXA)

We can clear the eng light and take it for a drive and it just runs slower than a wet week. runs perfect but slow.

Question is what could a wheel alignment shop do to make this continuously blow/short? could jump starting the car cause a serious fault to keep tripping this fuse?

As you would imagine the controllers for the inlet manifold (at the front) no longer actuate, im picking this and the cam shaft adjusters not receiving intel is whats making the car go into a limp mode.

#4

Engine light returned shortly after - any one had this issue?

Im sick of this car going to the shop and coming back worse than when it went in!

#5

Only thing I can think of is that the harness got pinched during the alignment and is now shorted. What the heck else could they have damaged?

#6

Yeah me too - could the Jump start do anything?

#7

How did they jump it? From the connectors in the engine bay or elsewhere?

#8

Obviously if they correctly jumped the car there would be no issues and after looking at the electronic dig for the car there looks to be a power regulator. The car system can take 18v with no issue so you can really jump the car with lots of power and not have any issues.

now if they jumped the posts backwards by mistake that could cause all kinds of issues. Check your jump posts for any chunks taken out. When you backwards jump a car it melts the posts and it leaves a big mark behind.

As for limp mode if you can post more of the vag data the data there will tell you what issues are putting the car in limp mode. Lowered mph will always be from communication errors FYI

Hey all the auto sparky has found that the top/upper inlet manifold motor has failed. And is shorting out causing the codes / eng light.
As I have a gutted inlet manifold the motor in question moves nothing!

I don’t want to have to buy a motor that does nothing, I’m waiting for a new manifold to be released that will come with all the hardware.

Would anyone have a spare or old manny with one of these motors on it doing nothing??

#12

Just unplug the motor. Just make sure its the motor and not the knock sensors. If the motor is unplugged you won’t go into limp mode but you will have a CEL after a while.

#13

yep that is exactly what we have done, the bottom flaps (that come on during cold start) no longer move at all either so the car has even less bottom end than before but its drivable for now…

#14

Update the car drives exactly as before with this fault just a engine light remains on.
Looks like the im s are coming back in stock so I’ll be jumping on that band wagon as soon as I can

#15

So it drives good its just down on power and you have a cel correct.

#16

It feels very similar to before - I believe its even softer down low, i.e weezier - but still storms up top. The motor had completely burnt out, melted plastic coming out of assembly holes etc.

Eng light remains on, my VAGCOM style cable arrived today so ill be able to keep an I on her.

Seems the IMs are only coming out in dribs and drabs which is a tad stink…I little boy waits.
