105 tdi starting issue

[teeth2k]

Hi
Can anybody shed any light on what to check
1.9 tdi 105 engine
New glow plugs

Taking 5-6 turns before it comes to life, no smoke

I have looked about but cannot work out what to check first

From cold or from hot?

From both hot and cold
Have read somewhere on the net it could possibly be the lift pump?

If it does it consistently a battery going bad or the starter are always the usual suspects.

Also the glow plugs are worth a check

Glow plugs renewed at the beginning of the month

See if you can try a different battery

I will have a look into that

Have you had the car scanned for codes? Think I've read somewhere the glow plug harness can be problematic although vcds would be my first move.

Tried to scan it yesterday but had trouble connecting my elm wifi adaptor, will try later today

ok ran 2 scans
first with dash command and fault read as follows
p0401 exhaust gas recirculation "a" flow insufficiant detected

second with ross tech and got
012295 camshaft position sensor (g40) no signal
p3007 000 intermitant

Our105 tdi altea would not start at all recently. Diferent reason to yours though (wires corroded)

Google search your fault codes and check on other forums for similar starting issues and same fault codes found. Your engine code is shared in lots of other platforms, you won't be the first person with this fault.

Does read like your cam position sensor needs replacing or there is a wiring fault with it though.

Good luck and report back with your progress please.

Iv just purchased a new crank position sensor and I will strip and clean the egr valve and manifold this week

 

[minimarvel]

You mean you bought a new Cam sensor right?

 

[teeth2k]

Camshaft sensor, that is the correct one right ?

 

[teeth2k]

After trying to find the various gaskets for the clean and not being able to work out which ones I needed iv decided to order myself a dark side egr delete

 

[minimarvel]

Your read fault code for Cam sensor then in your next post said that you have bought a crank sensor. They are not the same thing.

You may have to get your ECU software modified to delete the EGR not just a hardware mod. Google your engine code. Others would already have done it.

Silly question but what's the difference, I put my reg into euro parts and that's what I found,
Iv purchased HAAS Camshaft Sensor
Just my luck it's the wrong one!!!!
And yeh I understand I will need a remap, something I will look into but not really looking for a map for more power

I swapped out my EGR for a new one (70quid) at the weekend and its made a big difference. its only one Gasket you need the others are rubber seals between the Anti Shudder Valve(SP?) and the EGR to manifold. If you just take the ASV off you can get really good access to clean the EGR with a tooth brush and you wouldn't need to mess with the gasket on the side...

Egr delete arrived today, fitted and found the car to be a lot more responsive. While fitting I found the cam sensor unplugged, plugged back in and car would not start, unplugged and car started so I guess that's faulty.
