X16XEL miettii kolmessa tonnissa

[matukko]

Eli '97 Vectra B kovemmin kiihdyttäessä ikäänkuin pupeltaa vähän aikaa jossain 3000rpm kahta puolen, kunnes sitten potkaisee itsensä raivoisaan laukkaan. Muutoin toimii mielestäni ihan ok, koko rpm alueella. Miltähän puolelta osaisi vikaa alkaa etsimään?

minullakin samnatyyppisessä koneessa samahomma lähtee kiihtyyn kunnolla jossain 2800 kiereksen tienoilla en kyl tiedä et mikä tälläisen "piikkiilmiön" tekee ja muuten mulla kyl toi nyt toimii ihan ok

Saattais johtua EGR-venttiilin väärästä asennosta.
Tuossa Field Remedy, , joka tosin koskee ennemminkin X18XE ja XE1 koneita, mutta oireet sopii :

Field Remedy: 1252
Subject: Engine - Hesitation TC P0400 or P1405 is set
Models: Engines: Option:
Vectra-B 96...2000,Zafira 99...2000,Astra-G 98...99,5 X18XE1,X18XE1,X16SZR| X18XE1
Complaint: Hesitation while driving around between 40 - 80 km/h with constant speed. While accelerating the engine hesitates up to the 3000 RPM. Also during deceleration the engine hesitates. Above 120 km/h there are no driving problems. Sometimes DTC P0400 or P1405 is set.
Cause: Faulty PPS signal (Valve Position Sensor).
Production: As of production date 24392 all EGR valves are OK.

Remedy:
In case of complaints, please check first the production date.

Checking procedure:


View from above on the valve, connector in your direction, there you will find several number/letter combinations.

Example: 24392

Step 1:Check Delphi part-number (I)
If the number is 00272, the EGR-valve is OK.
If the number is 98055, continue with step 2.
Step 2: Read build date number (II) like 243 9 2.
243 9 2
| | |
| | Shift:1 = 1. shift
| | 2 = 2. shift
| |
| Build year:7 - 1997
| 8 - 1998
| 9 - 1999
| 0 - 2000
|
Build day: 001-365
Step 3:Identify 4th digit (build year).
If there is a "0", the EGR-valve is OK.
If the number is "5" or "6" or "7" or "8",
the EGR-valve is NOK.
If there is a "9", continue with step 4!
Step 4:Check the 1st - 3rd digit (build day).
If the number is from 244 to 365, the EGR-valve is OK.
If the number is from 001 to 243, the EGR-valve is NOK.
Only if the EGR valve turns out to be NOK according to the checking procedure,
replace EGR valve.
Read an delete troublecode,
- see workling procedure in the respective Testing-Instruction.
Removal and refit of EGR-valve is described in the Service- Instruction of
Astra-G - see operation "EGR-valve, remove and install" in unit "L".
