Default "Service Vehicle Soon"

The owner's manual is distinctly unhelpful about what this DIC message portends ("something electric may be wrong" or some such useless twaddle). Anyone had experiences with this particular warning so I can at least narrow it down before I get to the dealer? Thanks.

Is your SVS alarm constant or only when experiencing excessive traction problems when racing?

Racing? Ah, no... The first was definitely right after a particularly severe road shock (gotta love New England roads, even in summer) that may have lifted the rear wheels; the second didn't seem to be connected in that way but might have been. No observable symptoms in any vehicle systems either.

This will show you how to read your codes Forum Tech tips and after you write down the codes scan thru each module in the manual diagnostics section and reset the codes if the light stays off then it was probably just a glitch, if the light comes back on then you should post the code here and we'll take it from there

Dayum! That's cool. I'll try to absorb this and see what it says... Thanks.

The Forum rocks! I think this narrows it down:

10 Powertrain Control Module
- P1652H = Powertrain Induced Chassis Pitch Output Circuit
60 Instument Panel
- B0516H = Speedometer Signal Circuit Malfunction
- U1160H = Loss of Communication with LDCM
99 HVAC
- B0363H = Left Actuator Feedback Open
- B0367H = Right Actuator Feedback Open

The last two, if in fact problems, are largely irrelevant. The HVAC works fine.

The first three are all consistent with a sharp road shock that unloaded front and/or rear wheel(s). Which means that first big bump of the morning.

Thanks, guys, now I can be reasonably confident it's not going to puke its guts before I can have the dealer look at it (there are some other things pending as well).

All of your codes are history (H) codes so there is no ongoing problem. I keep a log of the codes from my car, date and mileage, then erase the codes and check them again in six months or a year. That way you can get a history if the same codes continously come back.

The (Service Vehicle Soon) message in today's vehicles generally is saying that an emissions problem has been detected. If the car is running fine, then there probably isn't a serious situation to attend to. I was recently at the dealer with this message and the service desk attendent went straight to the gas cap to removed it and retighten it. He said this cures about 80% of the Service Vehicle codes. The car must be restarted a fixed number of times before the computer resets. He said since it was running fine, drive it for a week and if the message was still there, bring it back. I never had to take it back, the message went away. You might give it a try to see what happens.

Yeah, I went through that gas cap thing on my Toyota truck, kept triggering the "check engine" light. Went round and round getting that one fixed.

Service Vehicle Soon can highlight several body and chassis problems. I had it come on after the power steering rack was replaced and the tech did not orient the steering wheel correctly. A few miles down the road the warning came on. When I got back they found they had to disconnect the steering and spin the steering wheel around 360 degrees to get the sensor to line up properly.

Bill, I remember you diagnosed my mystery loose wire on this car earlier this year and the service tech was even impressed that I could point them to look in the right direction! Well, I've never had the wheel off, but now I can be confident that the car isn't going to die on me and will have them look at it along with the dead HUD.

Your right about the last 2, I get them also and the "loss of Communication is also common and can be disregarded. I'm not sure about the B0516 code ??? that ones strange but since it's a history, no worries.

What caused your MIL lamp to come on is the P1652 which I've also never heard of (I'll have to look it up when I get home) but it looks like it's working fine now and I'm willing to bet if you haven't erased the code then after 4 or 5 cycles the light will go out on it's own.

My guess is that the 1652 had to do with a sudden vertical shock (it talks about "pitch" as opposed to yaw or roll) that somehow overwhelmed the BCM. None of these has persisted; that is, they appeared once, disappeared when I hit Reset, and have not recurred. Thanks all for the insights.

Actually, if you've never had the first hand experience, our road quality here in New England will do quite well enough, thank you. This particular road gouge I can usually straddle, except when I'm dodging Mom in her SUV in the next lane as was the case yesterday.

I got the dreaded "service vehicle soon" with a bad steering wheel position sensor. Didn't set a code. Hope this helps.

Hi All...I just joined this forum and just had this same SVS problem. The info you guys provided is great...especially you runamuck with the link to the DTC codes. Now I can look mine up too. Thanks again.

I just got this B0516 code all by itself. This was just after some very spirited driving/burnouts and hitting rev limiter while holding in frirst gear on my A4. I have a recent 3.42 gear mod and assumed it was from this.

Followup: it comes as no surprise that the dealer tech announces that he cannot go any further since all these codes are H, i.e. intermittent failures and not current problems (nor causing any obvious degradation in the operation of the vehicle). So I'm just supposed to watch for their possible reappearance. Sigh.
On a somewhat related note, the presence of slight transaxle leakage after replacement of the seals (more than once) even according to the latest TSB - now the "remedy" is to replace the rear cover and see if that cures "the piddles". Double sigh.
