Weight: Don't be fooled! (or Weight: Misleading!) | Posts 32+

Hello,

The basic version, weighing 1120 kg, only achieves that weight in an empty state with full tanks and a standard driver (which already adds 75 kg, so you've already gained 5 kg). Believe me, there's hardly any room for additional equipment (4 doors + 50 kg, air conditioning + 20 kg, radio system + 7 kg, CD changer 3 kg, sunroof + 15 kg, tow hitch + 50 kg, airbag system, which was still an optional extra back then + 10 kg, fog lights + 4 kg...). You quickly end up with several hundred kilograms of additional equipment, because even small things add up. Mine is registered as weighing 1195 kg (which is unbelievable!), and I'm only 5 kg heavier than the standard driver, but the car weighs 1400 kg (sunroof, air conditioning, tow hitch, 2 airbags).
By the way, at the very bottom of the Golf's vehicle registration document, below the number 33, there's the line: "SEE ITEM 14: UP TO 1281 KG, DEPENDING ON EQUIPMENT." ... That's already 84 kg more than what's stated directly under item 14!!!
Sometimes I also suspect that the empty weights are being manipulated downwards as well.

The rod on the pressure cylinder seems to be working; it's definitely moving smoothly.
I've also driven with the exhaust system removed, and it wasn't related to the catalytic converter or anything like that.

I have an appointment with VW for the day after tomorrow, and I hope they'll be able to fix it.

My diagnostic adapter isn't working properly .
It's probably due to the optocouplers.


I will definitely write back and let you know what it was, once I find out.

Best regards,
Jan.

Hi, I went to VW today and managed to convince the master mechanic to take the car for a test drive. Afterwards, he checked the diagnostic system, but there were no error codes.
'But even at VW, they couldn't find anything wrong. Even one of the older master mechanics who drives a 1Z said he was completely satisfied, and that there's nothing missing in terms of performance. Then they installed a different Mass Air Flow sensor (MAF) for me, even though mine is new. I took the car back and tried the new MAF, but of course, the same problem occurred: it cuts out at 170 km/h. I'll go back tomorrow and have them install my old MAF. They didn't want to connect to the data blocks. It's a good thing I finished building my diagnostic adapter '.


Price: €20 for the labor involved in replacing the LMM (lambda sensor) and checking the catalytic converter.
very 'affordable,' I think.

(maybe it was also because I mentioned that I would 'probably' have the inspection done by them next month! which, of course, I won't do ).

Okay, that was my day at VW .

Okay, since I'm currently feeling like my 1.4L engine is a bit sluggish, I did a test drive using VCDS (VAG-COM).

The air mass reading is 330 at idle and approximately 860 at 140 km/h in 4th gear.
Pressure is a maximum of 1860 (with brief overshoots up to 2000).
The ambient pressure is 1020.

I can't seem to find the table that shows the approximate values, maybe I'm just not good at searching, or perhaps the title of the topic has been changed.

The other measuring blocks are actually within the tolerance range, as indicated in VAGCOM.
Does anyone have the explanation for the values in the first block again?

Fault code generator error (1117) was present, but it could be cleared and has not reappeared.

What I had recently:
When accelerating from second gear with full throttle, there was a brief drop in power.
It's like momentarily releasing the accelerator for about one second and then immediately pressing it down again.

Perhaps someone has some tips on which blocks are worth observing.
My laptop has a new battery, so I'm ready for a test run.


Sincerely,
Jan.

'Thanks, I just couldn't find the way there.'

I've now compared the values, and I've noticed that my pressure is about 100 mbar too low, and my voltage regulator's slide valve seems a bit high at 4V when running at full throttle .
'Do you have any ideas?'
