Do you know when it was last serviced?

The surge that you feel will be the turbo kicking in.

 

Thanks for getting back to me Coleman.

The last service was back in June 2012 and each service the car has had has been carried out by an official Vauxhall garage.

Oh, and it's done 53000 miles (mostly motorway miles).

Thanks
Craig

 

When did you last check the oil level - and what level is the oil showing on the dipstick?

Any metal to metal knocks need to be properly investigated - if you don't know much about cars then to be frank there isn't much advice we can give without being able to see and hear the car. You're probably best taking to your usual garage and ask them to listen to it from cold.

 

Hi Taurus, sorry for the delay replying.

I've just checked the oil and it's about 3/4 full.

The noise hasn't been so apparent recently - I was out at 9am this morning and didn't hear a peep out of it! Very strange! Reckon it's worth taking it to the garage then?

 

Hi guys,

I've finally taken the car to the Vauxhall garage and they've just rang to say the knocking noise is 'probably' down to the car needing 2 new fuel injectors... at a total price of £669 fitted!!!!

As you can imagine, I'm reluctant to spend so much money. Can anyone offer any advice? Could this knocking noise in the engine be related to the fuel injectors?

Thanks
Craig

 

We can't really advise unless we can hear the noise from a video or in person and even then it's a guess most of the time.

Faulty injectors can cause a noise, but it's normally a ticking noise.

 

if theyre over injecting then yes, you'll hear diesel knock, which sounds metallic.

 

OK as requested, I've done a video of the knocking noise (filmed this morning - apologies for the quality) - see if you can hear the noise in the background at about 4 seconds in (my phone didn't pick it up great, but you can hear it if you listen a few times).

I can make it happen every time if I accelerate in too high a gear ie. 15mph in 3rd gear.

 

I can't really tell anything from that video. Can you get one of it making that noise from outside the car?

 

I will try - thanks for looking :thumbs_up:

 

My girlfriend has a similar problem in terms of sluggishness with her 1.3 ecoflex and found this thread.

I did the pedal test to check for the error code and it came up with nothing. I then took it to a mechanic friend who has a diagnostics reading machine and that too came up with nothing.

He noticed that it was misfiring (the car shaking when revved to about 2000 revs). He then isolated each of the fuel injectors using the diagnostics machine and it was clear that the 4th injector was not working.

He's sorting out all of the fuel injectors later this week; 3 of them cleaned and one replaced with a refurb. The replacement one will cost about £150 inc labour.

I'll let you know how I get on.

 

Thanks gmc1001 - it's good to know I'm not the only one with the issue (sorry)! Does the car have a knocking noise when travelling slow in too high a gear ie. 15mph in 3rd?

I'm gonna have to find myself another garage (not an official vauxhall one) to see what they find. Maybe getting a refurb will do the trick for me. According to the garage, injector 4 is dead and number 3 is on it's way out.

If you can let me know how you get on, I'd be grateful! Thanks

 

Apologies for going on, but I've been reading up online and wondered if it is normal for fuel injectors to pack in at so low mileage (53000)? My car is only 4 years old and has been serviced 3 times by Vauxhall and once by KwikFit (last year). The majority of miles are motorway miles.

Reckon I'd get anywhere if I went back to Vauxhall and said the car isn't fit for purpose (sale of goods act)? I know it's out of warranty, and can understand things go wrong... but £669 worth of work for 2 injectors is surely extreme considering the cars usage! Fair enough tyres / brake pads / discs need replacing due to wear and tear, but fuel injectors?

Also, would redex maybe fix the issue with fuel injectors? Vauxhall advised injector 4 needs replacing and injector 3 is on its way out - reckon it's worth a shot?

Maybe it's time for me to invest in a Haynes manual!?

To be honest it's a FIAT engine and they're known to be troublesome once they've done towards 60k. I'd get it sorted at a good independent and get shut of it to be honest.

 

My corsa has a fiat engine... Really? Didn't know that!

I only bought a diesel so it was last longer alm: maybe I can just sell it to a garage... They may not spot the issues
