VW Golf MK5 - NO POWER - anaru69

hi, I have a MK5 Golf 1.6 fsi (BLF) that has no power. it starts and runs fine but when you accelerate it is like the handbrake is on. I have scanned the ECU and come back with a P000A fault "A" camshaft position slow response ( bank1 ).

I have replaced the timing chain and tensioner, camshaft position sensor, coils, spark plugs, oil and filters, and whilst the sump was off I cleaned out the oil pickup and checked the oil pump, all to no avail. Any suggestions would be greatly appreciated.

Do you still have the same fault code logged?

Yes same fault code. i have pulled out the N205 camshaft solenoid and tested on the bench and seams to be working ( clicking ) but i'm not sure how much movement it is meant to have.

The obvious thing to suspect is the valve timing. You said you replaced the timing chain so are you sure you've fitted it correctly? Before you dismantle it try connecting a vacuum gauge on the inlet manifold. Normal vacuum should be around 21in-hg at idle. A steady reading of 10 - 15 in-hg at idle would indicate late valve timing.

OP check your cam follower. I believe it is is underneath the High pressure fuel pump. Check post #30 here: forums.vwvortex.com/showthread.php?4560756-WTF-is-...r-(Bank-1-Intake)/page2

If the cam follower is good then I would change the N205.

Co-incidently I took out my N205 yesterday to check for dirt build etc as I my engine was pinging under load but it wasn't too bad. I have a 2005 BLP engine. There seems to be so many issues with the FSI engine unfortunately. Just to drag it off topic - have you ever experienced any pinging under load e.g. going up hill?

Yes if you accelerate hard trying to go up a hill it does ping.

When replacing the timing chain i used the correct tools, ie; rear locking plate for the camshaft and DTI gauge on number 1 cylinder. Being the 1.6 ther is no lock for the Crank.

I have also removed and cleaned the N205 solenoid and bench tested it, it seems to be operating ok. I've checked the cam follower as you suggested and it is still in one piece.

Thanks i shall check vacuum and see what it is reading.

Hey guys, Just connected up a vacuum gauge and i'm getting a reading of around 17 in-hg

Before going to the trouble of dismantling anything I would replace the N205 with an used one to rule it out. Ross-tech suggest N205 being the likely culprit.

The vvt system works on oil pressure.May be an idea to check actual pressure first. Should be at least 2 bar @ 2000 rpm ,engine hot.

That's too low. Normal vacuum should be around 21in-hg at sea level. Subtract 1 in-hg for every 1000ft above sea level. If the needle is steady (which it should be) you either have incorrect valve timing or a small vacuum leak.

Remove No1 spark plug and drop a long thin screwdriver down the plug hole and rests on the top of the piston. Now obviously don't drop anything down that you can't then get out. Sorry to have to say that but I needed to make sure. Turn the enfine over slowly until the piston is at Top Dead Centre. When it is it'll either be firing on No1 or No4. Look at the position of the valves on those two cylinders. On one of them the exhaust valve should be just at the point of closing and the inlet valve just at the point of opening. This is known as 'On The Rock'. If for example this is on No1 then No4 is firing and vice-versa. If the valves are not on the rock then the valve timing is incorrect.

Further to my previous post you could have a blocked exhaust. To check this connect your vacuum gauge again and start the engine. Now slowly increase the engine speed up to about 3,000rpm. The needle should stay pretty much still or even increase slightly. If it drops steadily whilst increasing the speed you probably excessive exhaust back pressure.

Thanks for all the feedback guys. Problem is now resolved. Both cats melted and further enquiring found previous owners were running 91 RON petrol. Replaced cats and filled with 98 RON. Running as it should now.
