Nightmare first day of G60 ownership - please help :o(

[raddo_g60 0]

Took my new baby out for first real drive this morning. All was going fine until about 3/4s of the way through drive after about 20 minutes. I have a problem I think with performance anyway in that everyone always says g60s should pull from very low down. Well mine has to be revved a lot and feels more like a vr6 to drive.

 

This morning after bout 20 minutes whenever I floored it, instead of suddenly getting the rush of boost at around 3.5 / 4k revs, it got to about 4.5k then suddenly stopped and revs wouldnt go any higher like it had run out of fuel and was making a spluttery kind of im buggered noise and dint rev any higher until I lifted off and on the gas a few times. Even then it would do the same a little more up the revs at about 5.5k. Then after this happened the car started to develop a knocking noise from under the bonnet. I had a look when i got out and couldnt really tell if it was coming from inside the engine or not. But basically it knocked fairly quickly at idle then when I revved it it would knock even quicker as the revs rose. Whether this is linked to performance problem I dont know.

 

Also the bonnet wont close properly on the passenger side I just noticed. :( :(

 

Not happy really. Feel like Ive bought a dog. Everything was fine the other day though.

 

Please help

Regards

Engine doesnt sound to healthy if its knocking, could be bottom end problems. Its not a ticking type noise is it? Tappets?

 

As for the bonnet the release mech can sometimes sitck. Make sure the release handle has returned to its proper position and then go round the mechansim's under the slam panel, lubing them as you go to make sure they are free. If you look in one of the other sections you will see what happens if you drive with a loose bonnet.

Hmmmm.....rattling noise, no boost at 3.5K.......charger blown?

mate where are u as someone near u might be able to help :D

[raddo_g60 0]

kind of a ticking noise yes. Charger blown? How can I tell. I havent managed to test my boost pressure yet as cant get the mfa to do it. Every time I turn the car engine off the alarm/immobiliser doesnt like restarting the engine unless I do a whole get in teh car from scratch cycle.

Dont really understand what you mean by the bonnet and where to look for all these things. Sorry :(

God im so annoyed about this. nothing is going right with it yet.

Best thing to do is take it to a specialist to check over. Where are you ?

change yer fuel filter... ;)

 

Sounds like it may be as simple as a blocked filter and pinking... If you can also hear the fuel pump (kind of a whine from the rear of the car) I'd go with this one... Either way, the filter is about £10 and is pretty easy to change, so it's worth a shot... ;)

 

Good luck!

 

Oh, and let us know where you are... an opinion from someone who knows G60s won't cost you anything and may save you a lot of hassle... 8)

update: did an oil change last night and oil filter. Changing sparks today as well. Its still running badly with no low down pull and still misfires but only after running the car for a little while, i assume when it gets hot really. The most worrying thing is this knocking noise it has developed. It does sound like it is coming from the engine. But it could be somethign rubbing I guess? around the charger area. Do chargers develop knocking noises before they go bang then or do they just go one day?

Im so upset about this. Cant believe I may have got a dog g60. I suppose I could limp down to this gwerks/pitstop that you guys say is great. Which is th eone on the south coast that is meant to be good....I get confused. I bet they are all booked up anyways :? :(

raddo_g60, everyone else has asked, so I will as well: what is your location?

And Darren's lead time at G-Werks is never that bad, I'm sure they could squeeze in a diagnostic soon enough for you.

 

How many miles on the clock - do you have evidence/receipts of a charger rebuild? Should be done every 60k miles.

 

No harm in trying the fuel filter firstly though. It smells a bit, but only takes 5 mins to do.

[GazzaG60 0]

right you may have a blown charger you may not. lets not fear the worst just yet.

 

like henny says replace the fuel filter. this is located under the car drivers side just to the front of the rear wheel. tis a cylinder bout 6 inches long.

 

now for the charger stuff.

 

take of the black resonator box attached to the freont of the charger. it fastens to the charger with 1 bolt but you gotta get inside the box first. with this removed shine a torch into the charger and look for bits of metal and strips that are seals. they may have popped out and jammed or something (not good) best to do this before you drive it anymore.

 

engine noises.

 

it could be a bad tappet or dodgy rod bearings or maybe a pump such as water or PAS has gone bad.

[raddo_g60 0]

Sorry guys im in Hampshire! Yes I will try the fuel filter as well then I think. I checked the charger area and it has oil around the inside of the hose going directly into it. I thought this was expected? There were no signs of anything bad. I have a slight oil leak in that the underside of sump nad engine have a little bit of oil on. Saying that it hasnt leaked since the oil change yet so cant be that bad. Also, someone said about PAS pump gone...well...the power steering does make a lot of noise when it turns and i have some power steering fluid leaking underneath. I think. The ticking/tapping does sound engine or charger or osme kind of pully though. i dont know.

Perhaps I should check my boost levels. I just cant get the mfa to give any readings like I should be seeing though in the guide to how to bring up the boost on mfa.

I found this thread: (not sure if its related ) http://the-corrado.net/.archive/forum/viewtopic.php?t=3556&start=0

[GazzaG60 0]

the charger inlet may have some oil in there where its been returned. this may be due to an oil seal in the charger going and passing it straight back to the charger.

 

as you look down on the charger the res box is on the right attached to the charger. remove this and look inside the charger.

 

thats were the carnage may be.

[h100vw 0]

In my experience, chargers rumble when they need bearings. I suggest you take the charger/alternator belt off and run the engine briefly. No cooling as teh water pump will not be spinning.

 

You need to make sure it is clear of the rotating pullies but it is a good way of eliminating the charger/water pump and alternator from the equation. If the noise is stil there it is in the engine or PS pump. Big ends like Gazza says or maybe tappets.

 

If the noise is gone then it could be the alternator, charger or water pump.

 

Should I cancel the loom??

update guys:

 

Took car out today for a little test. Dont really want to be driving it hard with this problem but the misfire kind of issue has settled down. instead it just seems to progressively badly perform now if that makes any sense. Just seems reluctant to make progress really and just feels slow. Def reckon there could be a boost leak as can hear a lot of air wooshing. Im not sure where the boost reading is taken from n standard g60 but i finally made sense of the figures today and measured my boost level...well....i got a reading of (it might have gone over this but the max i ever saw it get to was 1790. Which apparently is (according to sns website) probably just under 11.6 psi. The charger is standard. So this tends to rule out a charger issue.

 

Still making the knocking joise having warmed up though. Hmm...

 

Thanks for all your help so far when I get some money may get myself down to gwerks etc.

 

PS: Also get a slight movement in the clutch when pulling away slowly. Kind of jabs upwards a tiny bit. Any ideas? Not major at all.

if you want to drop down for a cuppa and free health check please feel free... :lol:

[raddo_g60 0]

arr cheers g-man sounds like a good idea. When is a good time for you this week and does the health check include opening up the old charger as well? Im interested in getting a few things done for sure.

I know exactly what you mean, my G60 does it occasionally. It's either the clutch master cylinder or slave cylinder, nothing much to worry about yet unless the clutch won't return properly or ends up stuck on the floor. Sounds like you've got bigger things to worry about at the moment!
