Some of the romanian owners of VRS TDI PD's have complained that after this update the car didn't felt as powerfull as before. On dyno tests the results ware very disapointing 156 HP and 327 NM.

To be honest i didn't felt any power loss but the maximum speed has decresed allot.

If before the car managed 235 km/h (on the clock) now it only does 200 km/h and after a verrrrrrrrrrrrry long time 210-215 km/h.

I made some acceleration test uning vag com and the time for 0-100 km/h was 8.3 seconds. I got this result 3 times out of 5.

The consumption also seems to be a little higher by about 0.5 litres on 100 km

Did any of you noticed any differences after the update?

PS:Sorry about my english

The update remaps the car with a different map that is more DPF friendly, so things such as fuel/air mixture and other settings will have been altered to make the DPF last longer.

Its also possible that since your car is now older, the DPF is now more clogged up and this will have an impact on power and top speed.

The car isn't that old. It only has 38.000 km or ~23600 miles. About half of this mileage was made after the 26E6 update.

The "Update" was made on 24.11.2008 but i didn't noticed big differences until i tried to reack the maximum speed again. I only did this because of reading on a german forum about this problem. They also claimed that the cars won't go past 210 km/h after the 26E6 action. However there are some of them that say the speedo goes all the way up to 240 km/h the same as before the update.

From my experience and with the proof of a rolling road test pre (Feb '08) and post (Sep '08) 26E6 remap (done July '08) I'd say there is no difference. Tested on different rolling roads the results were within 2bhp of each other, which I feel is pretty spot on.

Immediately after my 26E6 upgrade, a little over a year ago, the car did initially feel 'flat' but having covered 250+ miles it was back to 'full health' having re-learnt my driving, fuel etc.

If you are getting the drop in power and performance as suggested I'd be straight back to my dealer as I'm sure something is 'wrong' which the dealer ought to be fixing.

In my experience it does loose topspeed after the 26E6 update.

But it will not loose power on a rolling road. Because on a rolling road you hardly ever use 6th gear.

After the update the power in 6th gear will be reduced from 4000rpm on. That is why most of the updated PD TDI drivers complain as if they are driving into a wall. Even after chipping it will still have this point where it seems to "stick" and wont accelerated any further. Only if the road goes more than 5% downhill or you are supported by a good slipstream, you can go faster.

It is pretty annoying, especially after a chip. It will accelerated faster than std, but still wont run any faster than approx 4200 on the rev counter (a bit more than 4050 on the CAN BUS).

(also the newer 2.0TSI is limited in 6th at about 6100. So even when chipped, it will not run more than 6100 in 6th.)

I'm afraid we can only dream of those sorts of speeds here in UK! :(

Best I can do is 'red-line' in 4th (runs easily to 4,500-4,750rpm) or 3,000rpm(ish) in 6th. What if I try going to the red-line in 5th; will the drop off in power be apparent?

I spoted today a "whistle" like sound comming from the engine at about 2000 rpm or higher when i lift my foot off the acceleration pedal. It sound like a hose is loose or has a puncture in it. Could it be that the car can't go passed the speed mentioned at the start of the topic because of this?

I'll try taking it back to the dealer tomorow to see what is all about?

Hi Guy

That is why I write down my experiences in this forum. I can test my car every week (and do, if traffic allows) on the same autobahns under different weather conditions.

(dont want to make you all jealous though!).

Redlining can be done in all other gears, you will not notice the flat spot at an indicated 4200. Can go beyond 4500 in 5 th if I want (did it once, just to try).

Coming back from the Ring yesterday on the A1 (autobahn), I almost had no traffic and the autobahn goes downhill for a long time. Here I managed to go beyond the flat spot at 4200. Before getting into traffic I touched an indicated 4600 in 6th.

But on normal not declining straights it will stay at an indicated 4200 as if treated with superglue

(redline in 5th is beyond 205km/h, better not try that in GB. Dont want you to loose your licence).

I have a medium uphill stretch on the M-way near home that I love to use the TDI's torque on (when most other cars struggle) got up to around 4,200 in 5th last night and car was still pulling really hard but then had to back off for traffic.

Guess if I have a problem with mine (which I don't believe I have), that is not apparent to me, it isn't going to matter unless I ever come over to the Autobahns.

However, I must say that I'm really amazed that Skoda would knowingly throttle back the power delivery on a car! :eek:

It is not just Skoda, it is the entire VAG range fitted with this engine.

It is well known that the 170PD has troubles with the DPF. Not the DPF on its own, but the management system that controls the bl**dy thing.

That is why they castrated the car in 6th, so the engine/exhausttemp/DPF will not overheat and kill the engine or the DPF.

Also the piezo PD elements get clogged if driven fast over a long time.

But if you dont have the opportunity to check it more often, you will never notice the loss of topspeed. And than you can still enjoy the strong (torquey) pick up the engine has. In the lower gears the engine will have its power.

So at the end of the day if you are comparing the PD170 and the CR170 (with the disadvantages of CR) you are caught 'between a rock and a hard place'.

Oh well; at least knowing that I will never (in UK) be able to try a Vmax run I will never know what I am (not) missing.

There are enough german drivers that not often try their topspeed. If you dont, you will never notice. After the 26E6 some of the owners even reported better power delivery in 6th from approx 120-200.

But if you never drive much faster than 210 you wont notice. And for driving over 210 you will need a proper stretch of free autobahn and that is a thing that is getting rare here too :thumbdwn:.

Getting a 26E6 car on a rolling road will confirm the power of the engine (if the PD elements arent clogged), but in real life the car wont run over 4000 in 6th.

That's perfectly true.

Some owners in Romania also reported loss of power. On dyno some got disapointing figures. For example 156 HP and 320 NM.

So, lucky me since I had it checked by my Skoda garage and no campaign is active for my VRS PD (and figures are similar to mike's )

Hi, I have the 26E6 update and managed 164.3 whp and 410Nm of torque on a superflow dyno. I was surprised because the car is standard, Octavia 2 vrs tdi, 2007 with 40 000km.
