Diesel Accord Manifold

Hi, don't know if anyone can help, but I have just had the manifold and timing chain replaced under the extended warranty Honda have on my 05 plate Accord CDTI.

However, the VSA light is now on constantly and the turbo is making a funny sound (almost like it is dumping as it is boosting!!), as well as a lack of power - all things that I never had before it went in for repair! Honda are taking it back in to try and find the source of the turbo noise and power loss, but claim that the VSA light has nothing to do with what they have done.

I'm not quite sure how the whole VSA thing works, but what I do know is that I have never seen the light on before unless I've manually turned it off. Does anyone know what could have happened to it while they were repairing the manifold and timing chain?

Thanks

(PS - I did see that this had happened to someone else, but could not read the thread as it was on THAOC: Google)

They could well have knocked something when they were messing about with the timing chain and mani. Insist that they sort it out, it's obviously something they've done.

If they won't budge, threaten to take the matter up with Honda UK.

If you take it on a rolling road you'll get the light come on for a few miles as well

See if it clears after 5 or so miles.

Loss of power after changing the exhaust manifold.
Sounds like the oil was not primed to the turbo or starvation.
The oil/water feeds need to be removed along with the turbo to change manifold.
In which case = new turbo thank you very much.

or the CAT could be blocked by some means like fluid or banging will cause a collapse of the core.

Anyway.....not your problem

Thanks for the replies so far.

I've done a couple of hundred miles now since I've had it back and the VSA light is still on. None of the other sounds have got any better either.

The four main issues of concern after getting it back from Honda were:

1 - Whirring/whining noise that sounds like it is coming from a belt or something
2 - Whooshing sound coming from the turbo (not the normal noise the turbo makes, but a strange one - almost like it is dumping as it is boosting!!)
3 - Distinct lack of power possibly down to the turbo kicking in late (if it kicks in at all!!) especially under load
4 - VSA light on constantly

It is now back at Honda, so hopefully they will sort all the problems out. I had it in there for 2 hours the other day and the mechanic didn't really have a clue what it could be - didn't fill me with much hope! One of his responses was "I've even started pulling off hoses which I know I put back correctly"...another was "the VSA has got nothing to do with what I was doing"... Hmm, strange how the light is now constantly on.

I've told them to keep it until the problem is sorted. If they do actually tell me what the problem is, I'll post back.

Thanks again

It could have been a induction pipe busted or popped off anywhere between turbo and engine (turbo boost leak).
It could also be a vacuum tube thats not connected (turbo boost control).

But if all the pipes are connected.... I'll still go with what I said before.
If the CAT is plugged the engine tries to force air out of any other orifice it can find ...or make a new one if it cant ...it will detroy the engine if driven with a plugged CAT.

VSA shouldn't have anything to do with they manifold/chain.
But if it was fine when it went in and now isnt its still their problem.

You got it spot on. One of the induction hoses wasn't fully engaged. That's that bit sorted.

The whirring/whining noise coming from the aux belt is apparently normal for these engines. Can't say I've ever noticed it as loud as what it is now, but I guess I'll have to live with that.

However, they are claiming no responsibility for the VSA light - no surprise there! I have already taken this up with Honda UK so should hear back in the next few days to see what they're going to do about it.

The code for the VSA is 66-1 and they say I need a new unit at £1600!!

Yeah... Id argue with that one and certainly the price
If it comes out with a new problem while on their premises its upto them to sort it out.

Aarrggh. Honda UK have just called back and are refusing to do anything to help with the VSA problem that appeared just a few miles after the major work Honda carried out on my car.

They are claiming it is an internal fault in the unit which could have not been affected in any way by the work that they carried out. They are also refusing hands down to contribute to any costs involved.

They just put it down to a coincidence!! Damn, I must be unlucky!!! 3 things to all go at once....

I will never buy a Honda again after having one for the last 10 years.

Anyone have any technical knowledge about how the VSA works and if the turbo not being correctly working when I drove it off could have caused the unit to fail?

Is there anyone beyond Honda UK that I can go to, to take this further?

Honda UK arent liable for a fault that occurs on a dealer forecourt.
Thats a dealer problem only.

If the car is under warranty then the VSA block is covered.

There is no relationship between turbo/manifod/chain and VSA.
The modulator block sits behind the bumper in the drivers side wing.
Its not in the engine bay.
The VSA brain is located elsewhere.....
But I would suggest seeing if the looms connection block is connected properly
If its an internal error it may be a wiring issue.

Have just been reading on another forum that it is quite common for this fault to occur when the car comes back from Honda for clutch, timing chain etc.

Seems to be a problem with this unit. Seems very strange to me that they are dying after coming back from repair.

Thanks for a bit more info about where the VSA module is.

The 66-1 error does indicate a fault within the module itself.

Sounds like far too much of a coincidence to me. I read somewhere on the old THAOC about someone having a similar problem and it ended up being because they'd banged something whilst doing work on the timing chain and dislodged some wiring.

I agree. If you follow the link in my first post to google, the first result is the link to the old THAOC forum (although it's down, the brief google synopsis says exactly that) - just wish I could have read the whole thread and what the outcome was.

Was it just a simple matter of sorting the wiring out or did the wiring issue cause the unit to fail?

I'm definitely going to take this one all the way to the bitter end....

Yeh, it's good news if your car has done 62000 miles or less, but unfortunately I've done almost 95000

My letter to Honda is going out today, so we'll see what their response is!

It is crap that they're limiting it to such a low mileage. Diesels are mostly bought by people who do lots of miles, it's what they do best, so this warranty extension really isn't worth a whole lot.

Good luck buddy , HUK wont budge they are a hard nut to crack lately. They are certainly clamping down on gesture of goodwill.

I would have opted to call them in the first instance than writing to them, letter would just get the standard formatted response .

Let us know how things pan out.

I did call Honda UK initially. They were unwilling to do anything. This was before the bulletin was formally announced for the VSA. I have now sent an email to the manager at the dealership as I believe any problems that happen while at the dealer is a dealer issue and not a Honda UK issue.

Should get a response next week.

JohnnyBoy has a valid point. I can't imagine there being many 5 or 6 year old diesels out there with less than 62000 miles on!! Mine had 67000 on it when it was 3 years old...

Not really, it's a pretty hollow gesture considering the expense of the problem. They know most people will be outside of that mileage range.

Totally agree with JohnnyBoy, and I suspect the high price is a big factor in that.

Does anyone know what actually fails within the modulator? The TSB says something goes open circuit, (is that right?), and the speculation is that taking a knock is the cause. Is it the kind of part that an inquisitive engineer could take apart and have a go at fixing? We know many bits get automatically replaced when a bit of time and patience can revive them. Does this have any chance of falling into that category?
