Lack of ASR and EDL on TDI

enough abbreviations for you?

Can anybody comment on not having ASR and EDL on the Jetta/Golf TDI's?
It's kind of disappointing as those seem like very desirable features.
I got the ESP, which, based on the literature, is something of a
superset of the ASR and EDL capabilities so it seems like it's just
that they disabled the software for the ASR and EDL.

I think the ASR was an option back when my TDI came out in 1999.5 - it's
listed in my owners manual, and my car has the light on the dash, but I
don't have it.


The ESP system reduced drive power when it's activated and senses wheel
slip... this is what ASR does.

What is EDL?? Do you mean EBD - Electronic Brake-force Distribution? Don't
think Golf's have this...

My 05 Passat TDI has ESP. It has 2 functions. When pulling away from
a stop (or other acceleration) if it senses wheel slip on the drive
wheels it applies the brake and (sometimes) cuts the throttle. I saw
the ESP light flash plenty when pulling away from a stop on snowy or
icey roads. I think that's all ASR ever was.

The second is the anti-skid. It's damned near impossible to put the
car into a skid. If you crank the wheel in a parking lot you can feel
the "inside" rear wheel braking and pulling it back straight. It will
also cut the throttle if needed. I was not able to get the Passat to
spin out, or even close, on a slippery parking lot (empty).

My assumption is that ESP is just the earlier ASR functions plus the
anti-skid stuff which is new.


As an aside, I just got the snow tires taken off today. (Michelin
X-Ice are fantastic in combination with ESP.) Tomorrow we're supposed
to get snow...

Hi Rob,

interesting. info. The EDL is "electronic differential lock". It's
supposed to brake the wheel that's spinning to give you consistent
drive wheel RPMs when the two wheels are on surfaces with differing
friction. I was really looking forward to it. c'est la vie!

Al - thanks for the practical info on the ESP and the snow tires. I'll
have to get a set next winter!

That seems to be one of the functions of ESP. My Passat does just
what you describe.

That was my impression as well but if you look at the brochure, at
least for the Jetta TDI, they show EDL and ASR as unavailable for that
model. Only the gas engines supposedly support those specific features.

I checked the Passat and all models come with EDL, ASR and TDI is an
available option. So I guess I'm SOL on the Jetta. Darn.

If you have ESP, seems like you have the best possible system.
