This code has been coming up more and more for me.

Address 34: Level Control Labels: 4E0-910-553.lbl

It is the only Address 34 Level Control code I get. I looked back through regular scans and found that it has been coming up since 10/2013, and about 20K miles have passed since this code started coming up regularly in my full system scans about every month. I cleared all codes lots since I have been trying to diagnose my secondary air system since around then. Still not fixed yet.

I didn't pay a lot of attention to this, because my focus was on SAI and I have no suspension issues that I am aware of.

I researched the forums and see that this is the pressure sensor in the valve block, that it precedes compressor failures sometimes. I think my compressor is working fine, it does not make noise and it does not come on repeatedly or excessively. I also am not aware of any sag issues when parked over time. Car has 132K now.

Any ideas?

I think that it might be a bad connection. Hopefully. So cleaning that harness with some contact spray may help. That's the only sensor that tells leveling module about air pressure. It has to work or system would be shut off. Intermittent sounds like a loose contact. I don't think that sensor would come back once broken.

Hello DA8,

When I bought my car over a year ago it was giving me the exact same error code, and only that one. (for level control at least).

After some searching, I eventually gave the repair kit from http://www.bagpipingandy.com a try, had it installed and since then, no more fault codes and a good working compressor for almost a year now. I've been reading good results from other readers too, so it's worth the 25 buck i'd say.

If reading A8 forums day in and out for over a year has taught me anything it's that that pressure sensor fault relates to low pressure and not a faulty sensor, as was mentioned get yourself a repair kit from bagpipeandy and you'll be good, ignore it for much longer and you can end up burning the compressor up, while your at it it would be money well spent to replace the relay the supplies the compressor

Hi,
I was driving when my ESP warning lamp and check engine light came on. I did a scan and i got a code for the MAF sensor and 1772 Signal Cable Of Pressure Sensor For Self Leveling Control G291.
I opened the Air Pump Relay and noticed a strong erosion of both contacts, overheated strands and burn marks on the Relay Housing.
Yesterday i changed the MAF sensor and erased the codes for the MAF sensor.
Since then, the check engine light and the ESP lights went off. I drove the car all day yesterday and drove it hard today and still no warning lights for the ESP or check engine.
Does it mean the compressor is still okay or do i still need to re kit the compressor?
I'll change the relay tomorrow and i intend traveling with the car next Monday, its an 8 hour trip one way.
Is it advisable to go on the trip with the car or should i re kit the compressor before embarking on the trip?

Thanks as always.

As I understand, the G291 is in the valve block. If the suspension is fine, then you shouldn't worry about it. After you drove the car, lock and do you hear compressor releases air?
Cheers,

I tried listening for the sound this morning, it released air but a very small amount of air or should i say sound was heard compared to what i used to hear.
Thanks.

Thanks, but how do i get to the suspension module output test/accumulator test, secondly what should i look out for when running the output tests?

Thanks once again.
