2.0TDi Engine Fault - Turbo??

Why do these things always happen on a Sunday evening when you can do nothing about it??

Anyway brief history and details.
Leon FR 2.0TDi 2010 just under 80K on the clock
Drove home on Friday, mainly motorway and dual carriageway 25 miles and everything seemed fine. Filled up on the way home at the Esso garage.
Later Friday drove about a 15 mile round trip. Noticed on a hill from a junction that the car felt a little sluggish but put it down to being full of fuel. Overtook a car on the lane and everything fine. Didn't really hammer it or need sharp acceleration other than that.
Drove car again during Sunday. Aircon on as hot! about 5miles each way. On way back on an incline again didn't feel much power. Put it down to the 4 people in car, full tank, aircon on etc. Again didn't really go for it as not needed.
So Sunday evening nearly a 30 mile round trip. About 5 miles in (same lane) went to overtake a slow car and part way through the manoeuvre the car flashed up with a engine fault and lost a lot of power. Quite worrying. Luckily it was a nice clear road. Car then felt like it had no turbo. Pulled in at the next safe place after a couple of minutes and cycled the ignition and everything back to normal so carried on. Came to a set of lights which happened to change on approach so accelerated in 5th from about 35/40. Very slow climb up the revs. No boost kicking in as expected and then the fault came again. Cycled ignition again to clear. Same thing happened on the way back home a third time at a higher speed and then the engine light also came on.

So 3 things. Filled up with Fuel, had aircon on a bit and it's been rather hot. I'm thinking these are all coincidental and there is another underlying fault...

So, the important bit, I've read out the fault codes as below. Now need some help as what I'm going to do next as no chance of getting the car in and out of work on a 50 mile trip in this state.
the first glow plug fault probably not so critical it's the second boost one I'm more concerned about. The speed and revs tie in to what I saw on the dash as was expecting this one.

Looking like an actuator fault.

Thought it would be simple getting a new part but unfortunately Dave has left Sere and they are not getting a replacement person for another few weeks.

Need to try and search other avenues now.....


Update: Managed to get a part from Mike at Listers Worcester. Did a good price and got the part in PDQ. Lets hope it fixes the problem

Turned out to be the actuator at fault with little to no vacuum so wouldn't operate the turbo vanes. Which after reading about is exactly what I told the garage to check. Guess they didn't do a vacuum check on it which is such a simple thing to do.

It also took the garage an age to replace it. Maybe if I'd took it to a specialist it would have been done a lot quicker.

Anyway, Got the car back and its running a lot better than it has been now that everything responds correctly. I guess the actuator has been on its way out for a while.

Ah! I remember reading this thread when you first posted and I meant to write a reply as I've just changed the actuator on my CR170 but I completely forgot!

Oh well, glad it's sorted! :)

Many hours reading around on the Sunday night lead me to the same conclusion. But thanks anyway.
Thought I'd update it in case anyone had the same.

Also found some good info on turbos and actuator operation including a few vids so helped with a better understanding.

How many miles had yours done before it needed replacement?

What do you mean the right side?

What car/engine are you on about? 2010 FR was running the 2.0 common-rail engine, CEGA.

Plastic manifold? That will be the intake manifold not the exhaust manifold/turbocharger.

The 170 CR should have the ASV and EGR valve on the intake manifold.

The motor on the side of the inlet manifold is the swirl flap adjuster.

According to Seat's technical documentation for the Mk2 Leon the CBBB engine was not used. All CR170 Mk2 Leons sold for the UK market should have the CEGA engine.

If you have a CBBB installed I'd be very interested to know if it's factory fitted or whether the engine's been replaced at some point.

just reviving this thread again sorry

I'm relatively new to the Seat Leon FR CR170's with the CEGA engine but how do I go about testing the actuator without a vacuum tester ?

I'm having to drive the car with this issue and it has been like this since I have put fuel in on Friday 28/6/19 V-Power diesel from shell ( very confused ) thinking it was fuel issue but I had the fuel tested and its fine no contaminations

I have check my vac pipes and hoses but no visible signs of a split or damage to anything boost pipes are all good so just needing conformation it could be the actuator that is at fault so I can strip the thing off and try test it some how with out a tester

I have what's sounds to be the same problem

P0299 code came up which I cleared but has since come back after the engine warning light came on and loss of boost.

When the boost does seem ok, the noise when blipping the throttle sounds louder than normal. Like I can hear the turbo

Could this be an indication the turbo vanes are not spinning/turning properly?

I've since sorted my umderboost issue with swapping out the actuator but I didn't get the noise you are describing

My issue was a failed diaphragm within the actuator. Not sure if this has led to any excessive wear on the turbo

I am thinking the noise was the pressure leaking from the diaphragm (but just a guess)

The actuator repair kit has been installed and comes with a 2 year warranty. Let's just hope the turbo itself holds out

This was cheaper than a whole new turbo unit
