Cam belt not done properly?

[Icecavern]

Had the cam belt on the LCR about a month or so ago and yesterday the check engine light came on. Managed to read the codes out tonight and got


2 DTCs Found:
16396 - Cam-Timing Adj. Bank 1: Retard Setpoint Not Reached
35-00 - -
16727 - Camshaft Position Sensor (G40): Signal too High
35-10 - - - Intermittent

Does this sound like a co-incidence or is it likely the cam belt hasn't been fitted properly?

Going to be calling Camberley Seat tomorrow to try and get it booked in again but wondering where I stand

Hmmmm will be playing hell with them if they've not adjusted it right. My wife uses it to drive around my son when they go anywhere

Do they come back if you erase them? a timing fault will normally re-appear within a few seconds of the engine running.

 

[Lodgey180]

does sound a little suspect..

Bit odd though if its taken a month to come back on.

You usually get a camshaft correlation fault not those two anyhow. I think the first fault will cause the second anyhow. If the timing adjuster on the cam chain is sticking then it will throw the cam position sensor out.

 

[Icecavern]

But dont you replace the adjuster when you change the belt?

 

[James_R]

No the chain end isnt touched on a belt change.

Is your engine making any unusual noises, struggling to start, lost any performance?

 

[Icecavern]

Ah right.

Yeah it's not starting right from cold, and it's not idling quite as normal.

 

[James_R]

The tensioner damper could have failed or the tensioner come loose there are alot of possibilities, just take it back to the dealer and ask them to check the timing.

 

[JamesL]

I know of a good indy in basingstoke it you need it Pete.

 

[techie]

Sounds like the tensioner has failed IMHO, not unheard of.

To be honest, I don't like Camberley Seat anyway, when I went in there they seemed like they didn't care about the problems my car had and didn't want to help. My mate has his car in there too and they had to remove the front bumper for a repair and didn't put it back on properly. It came loose and nearly fell off whilst he was driving it!
On the issue you have though, i'd check the tensioner damper as already said.

 

[Icecavern]

As an updtae, just got back form Camberley Seat. It's not the cambelt, but the timing is out. So they're having to strip bits down to find out the fault. Just by the look on the guys face I get the feeling this bill is gonna hurt

 

[LEE69]

The timing is out due to them fitting the belt a tooth out surely?
Any more and you'd be hitting valves to pistons?

 

[Icecavern]

No they say the cam belt timing is fine, but the chain might be out.

 

[LEE69]

But the chain wasn't touched was it?
I don't think they can "jump" out of timing on the chain?

 

[Icecavern]

No idea. The chain wouldn't be touched in the cambelt change AFAIK.

 

[LEE69]

Exactly, opposite side of the engine, and the sensor picks up the cambelt side

 

[James_R]

The chain cannot jump but can become slack due to low oil pressure not acting on the hydrolic tensioner. This may cause a timming fault. The car would run fine without any loss of power but would have a slight delay at speed when accelerating and sometimes the oil light would come on, well this is something we have seen on some 20vt engines with 90k+ miles on the clock. The oil feed pipe tends to block up causing the above symptoms.
