VAG-COM Version: Release 704.1

Address 35: Centr. Locks
Control Module Part Number: 8D0 862 257 E
Component and/or Version: CV-Pump, Alarm, RC D13
Software Coding: 13166
Work Shop Code: WSC 06325
3 Faults Found:

01370 - Alarm triggered by Interior Monitoring
35-00 - -
00955 - Key 1
09-00 - Adaptation Limit Surpassed
01134 - Alarm Horn (H12)

What do they mean and how can i fix them ??

Any tips for using Vag-com ??

Adam,

The central locking codes can be cleared and I would consider getting a new alarm sounder, The engine codes relating to the system too lean would IMO indicate a dead MAF and not sure about the coolant temp one but if it's the sensor I think it is I would get it changed out for the later blue one iirc which is the after run pump mod
but I could be wrong and will stand corrected by some of our more knowledgable fellow drivers

BTW, the engine wasn't running when i did the test.... Nor was the ignition switched on

[AdamS4]

Yeah, it looks like a dead MAF.... peak reading was 107 today.... way low.

Ordered a new one, should be here tomo or friday

[shineydave]

alarm - no communication is a knackered siren, probably the back up batteries have failed, new siren required or try to clag a seperate NiMH battery pack on the outside of the sounder to provide the back up power. you won't have any sound from the siren.

the others are fairly normal, i think the key 1 - adaption limit surpassed is because you haven't used the spare key for a while, pretty normal really

[AdamS4]

Thanks all

Do you happen to know where the siren is ?

[ChipHazzard]

the sounder is in the drivers side cubby hole in the boot

[shineydave]

pull the trim off the right hand side of the boot, there's a well down the side behind the wheel arch, siren is bolted to the boot floor just under the rear light

The coolant sensor is also a 'known' weak part.

[AdamS4]

Which one would it be ??

[GHH]

i had to do this on mine after gavster hooked me up with vagcom, my temp needle would occasionally drop off as well - it should be a 4 pin sensor marked "coolant temp sender f18/f54" on the pic. i picked up the blue sensor for the afterun pump too and did both while i was there. mine was well crusty and an arse to pull out once the retaining clip was slid out.

[Dippy]

I know it as the G2/G62 sensor. Not sure why it is shown on that page as F18/F54.

[AdamS4]

Right, i've just changed my MAF and them 1st codes have cleared.

But i've now got this code....

Try this on for size

[shineydave]

that's prolly a result of the damaged TBB
