Engine issues. Small, but building

[ThomasG]

OK, I am already depressed by the thought of the cost of this, but any insights may help me.

So, I noticed a lack of power when I put my foot down, the car seemed to take a bit to kick in. Turbo cleaner in a full tank...

I had also noticed a tapping noise when starting cold, goes when warm. Checked the oil, all ok.

Then I scanned the car and there are readings well out of synch with others on injector 5. So injector cleaner in...

Now, the car started misfiring when I started it up. On idle it juddered - 1.5k revs all fine. Read up a little and realised you have to sit with fairly high revs for a bit.

By now I had booked into garage, as they have a 2 week lead at the moment.

Started it yesterday and sat with high revs, all seems fine. 

Started it today to drive to garage, all fine - but the tapping is back (it's a cold day in Scotland today), and by the time I had drive 3 miles to the garage - all is well - I could accelerate well...

However, the garage say they no longer "do engine work" - it would be sent to Audi or to Border Engines in Berwick should they find a problem.

So - any ideas? I am dreading the cost of replacement injectors, or even worse a piston slap issue, or timing chain. It's at 116k miles, so maybe it's that. 

Bah

Hi Thomas , Do you have any Fault codes? Jasonj

Hi Jason, no - none. I just monitored the engine whilst running and got outputs outside what all the other injectors were showing...

[ThomasG]

Ahh ok. It's in the garage now...they are scanning and checking

Fingers-crossed, though I've just received a text to call them 😞

[ThomasG]

OK, they've called - it is injector 5 - they are going to replace, but have warned me it could be either a straightforward job, if it comes out no bother, or not if it's seized in. They are on a 3 week lead time at the moment - and they've given me a....Nissan Note for the runaround!! 08 plate, can't go into Glasgow with this either! LOL

Haha, we don't have those new-fangled food delivery services here 😉
