01 1.6 Passat VW sluggish , not responsive , no power

motrocco

serviced a lads vw passat 1.6 01 changing oil, oil filter, air filter, spark plugs thinking it would fix a problem with his car. 100k miles on it, TB not done, has service by VW til 66k. It's a dog, no rip in it, bithch basically won't move. Sounds like it has a misfire on opening throttle up, settles down once revs level, bounce in the throttle needle!!

Looking for easy way to read codes, then decided what bits to possibly swap out and check engine, to get it running right!

Any ideas before I get codes(or easy way to read them)? EPC light was on last time I ran it.
He's driving slowly to work this morning. Seemingly, used to do ton !++! plus EASY, but NOW WON'T pull 80 (yeah he drives the **** out of his cars on closed private roads).

I've sat in back seat, it's not moving at all. Help appreciated folks, plz.

UPDATE:- Have been advised to pull the Air Mass Meter and see if it drives the same. This should help eliminate that I think.

Was in it this morning and it drove fine for about 5 minutes then started acting up, no power when your floor it. Number 4 bus got very close, very quickly, not safe!!! :eek:

I hope its not this that is after packing it in! Considering that he drives his car so hard it could very well be. Petrol VAG engines are not great anyways and have poor reliability. As other poster, get a mechanic to have a look at it!

My OH drives a 02 1.6 golf,self same problems.
Very sluggish when accelerating,almost like a misfire.
Used to replace the"spark plug leads"? on advice from a mechanic,which would temporarily sort it out.
An absolute dog of a drive until recently when my mechanic did the timing belt @120,000 miles.
It's a different car completely,more responsive,powerful and greener too if the onboard computer is to be believed:rolleyes:

Have you checked the ignition coils?

Diagnostic check should show what sensor is gone. Your car is running in
"Limp Home Mode". Safety feature to stop any damage to the engine.
Sounds like your MAF or lamda sensor is gone. Get them replaced and the light reset and you'll be back motoring.

But that is normal from a VAG 1.6 litre engine. :pac::pac:

Seriously though, the most common problems with VAG engines seems to be with numerous oxygen sensors, lamba, MAF and throttle body. I would start by checking these, if you have access to VAG COM then there might be an ECU error code which will point you in the right direction.

BTW I am not a mechanic but my sister's Lupo suffered from similar problems to the point where it kept stalling and had to have the above done as part of the troubleshooting process. Ended up being a knackered throttle body sensor.

I would if I thought it would help but two of them have had a look and both had different ideas on the problem and causes and wanted LOADS of CASH for parts.

My mates not so flush so I offered to service it for him thinking that this would hopefully sort out the issue. Which it didn't, obviously!!

No offence to mechanics in greneral but there are those out there that don't have a clue and will WILLING replace parts willy-nilly AT a cost, hoping the problem goes away as opposed to identifying problem and best solution.

So far it's cost 80 odd yo yo, probably another 60 or so for codes to be read, THEN I'll look around for a GOOD mechanic that knows what he's talking about.

Thanks for the responses so far guys.

Can't read codes with VAG-COM then no?

Quigs Snr

I don't think Vag-com will tell you anything, but its worth a go. I had the same problem in a Bora. Lack of power. Unusual engine note, revving the hell out of it and no power like it had a speed limiter. Turns out the timing belt was out, it had been replaced 10k earlier and was frayed on the side due to a jammed pulley and basically the engine was running on one less cylinder...

Get it to a mechanic or your mate's next purchase might be a bin tag for the car...

P0422 - Main Catalyst Efficiency Below Threshold (Bank 1)

P0322 CKP / RPM sensor

http://www.passatworld.com/forums/showthread.php?t=213774&highlight=p0322 found this and read this http://www.passatworld.com/forums/showpost.php?p=1087253&postcount=11 other post too.

Will check both sensors, leads, grounds tomorrow. Should worried about second post mentioning cam chain tensioner. This would have a clicking sound and other codes mentioned no?

Car still driving the same.

Fishtits

Certainly carry out basic checks.

As both errors are ECM linked there could be an CAN arbitration issue as to which or both are in fact actually at fault, look for an expert if you get nowhere with the basic stuff would be my advice, this may turn out to be a simple problem but diagnosing it is the key.

CHECKED some wires with the wiggle test, engine still warm but hot enough to wiggle. Car pulled great, drove hard, immediately (immediatly) from start, could be a time thing as it did this already. I did think it was fixed already. Probably not.... BTW atleast teo inserts for mass air flow meter, the jap one MIGHT BE the first developed.

Going to change the rpm sensor / cam position sensor / chamshaft impluse ensor (same!). It's the cheapest electric part to start, every garage should have one, it's not the air mass meter atleast.

this explains some of the problems with air mass meters and the electrics behind it. Honestly I think it's all PRE-PROGRAMMED in the ECU for all cars. These are changeable for emmission pusposes. BY LAW

IT ALSO MEANS that the MAX amount of air at a certain pressure through that metal it measureable, and next you mix the petrol.

Get that right and vroom...



ANY AIR LEAKS WILL F******* with the shif, and MESS WITH THE M£T$R

pablosd

no offense but i heard they are dog slow anyways, friend had one and he said that the car was overheating quite often due to undepowered engine in such a heavy car,

vw dealer or indy would be the first place i'd go to have the problem checked out !!!

Nonoperational

Ah we know the 1.6 is a bit slow but thats definitely not the issue here.

I am OP. LOST ACCOUNT. Excuse please. Thanks for reading.

This is fixed.

Turned out it was the RPM sensor as outlined in the codes read. There were a couple of different ones (RPM), it was the one with the longest lead.

This part was about 25 euro, took a couple of hours to change, due to where it is in the engine. It's behind the fuel filter. The lead taken off was squashed / pinched a little from where someone else removing fuel filter had snagged it. Probably the cause of it going.


Reset codes again (great tool!!). Started it up and it ripped.
Problem sorted. No mechanic required. Code reader was a life saver.


Anyone know where I can get a cheap code reader?

Thanks for all the response.
